Description

Technical Field

[0001] The utility model belongs to the technical field of emergency equipment, and particularly relates to a sliding bucket device and an emergency equipment. Background Art

[0002] For high-meter-section aerial ladder fire trucks, due to the relatively high lifting height and limited load-bearing capacity of the ladder frame, it is not conducive to multiple people climbing at the same time; using the working bucket at the top of the ladder to directly extend and retract the amplitude for rescue, the action speed is slow and the rescue efficiency is low. Therefore, high-meter-section aerial ladder fire trucks are mostly equipped with a fast sliding bucket for transporting people up and down. The sliding bucket device mainly consists of a sliding bucket frame, a ladder frame guide rail, a winch, a rope mechanism, a braking mechanism, and a roller mechanism. The sliding bucket device is placed at the guide rail of the upper chord of the ladder frame and can slide along the ladder frame direction by being driven by a steel wire rope through multiple rows of parallel rollers when in use. The appearance of the sliding bucket device can greatly improve the efficiency and speed of multi-person rescue at high altitudes, which is equivalent to setting up an "air elevator" between the ground and the fire scene.

[0003] In order to facilitate transportation, the sliding bucket device is usually set in a structure form with a foldable bottom plate to reduce the space occupied after the sliding bucket device is folded.

[0063] The following will describe in detail the specific implementation manner of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific implementation manner described herein is only for the purpose of illustrating and explaining the present utility model, and is not used to limit the present utility model.

[0064] Next, the chute device 100 and the emergency equipment according to the present utility model will be described with reference to the accompanying drawings.

[0065] As Figure 1 shown, it is a schematic structural diagram of the chute device 100 provided according to an embodiment of the present utility model; as Figure 2 shown, it is a schematic structural diagram of the bottom plate support frame 50 provided according to an embodiment of the present utility model.

[0066] The chute device 100 moves relative to the sliding member. The chute device 100 includes:

[0067] A vertical plate support frame 40, extending vertically and close to one side of the sliding member;

[0068] A bottom plate support frame 50, with its first end rotatably connected to the vertical plate support frame 40;

[0069] A telescopic assembly 60, with both ends of the telescopic assembly 60 hinged to the vertical plate support frame 40 and the bottom plate support frame 50 respectively. The telescopic assembly 60 is used to assist the second end of the bottom plate support frame 50 to swing towards or away from the sliding member.

[0070] The vertical plate support frame 40 can be used to install the vertical plate of the chute device 100, and the bottom plate support frame 50 can be used to install the bottom plate of the chute device 100. The vertical plate support frame 40 extends vertically and is arranged on the side facing the sliding member. The bottom plate support frame 50 is rotatably connected to the vertical plate support frame 40. After the second end of the bottom plate support frame 50 rotates towards the vertical plate support frame 40, the space of the chute device 100 is reduced, which is convenient for transportation.

[0071] The sliding hopper device 100 provided by the embodiment of the present utility model includes a telescopic assembly 60. Both ends of the telescopic assembly 60 are hinged to the vertical plate support frame 40 and the bottom plate support frame 50 respectively, and the telescopic assembly 60 has a driving force downward along the axis. When the second end of the bottom plate support frame 50 of the sliding hopper device 100 folds towards the sliding member, the telescopic assembly 60 provides assistance to make it easier for the operator to fold the second end of the bottom plate support frame 50 towards the sliding member. When the second end of the bottom plate support frame 50 of the sliding hopper device 100 unfolds away from the sliding member, the telescopic assembly 60 can also provide assistance to make it easier for the operator to unfold the bottom plate support frame 50.

[0072] In one embodiment, as Figure 3 shown, it is a partial enlarged schematic diagram when the sliding hopper device 100 provided by the embodiment of the present utility model is unfolded. As Figure 4 shown, it is a partial enlarged schematic diagram when the sliding hopper device 100 provided by the embodiment of the present utility model is folded. The sliding member extends vertically. The hinge point of the telescopic assembly 60 and the bottom plate support frame 50 is the first hinge point, and the hinge point of the bottom plate support frame 50 and the vertical plate support frame 40 is the second hinge point; when the second end of the bottom plate support frame 50 is far from the sliding member, the first distance between the first hinge point and the sliding member is less than the second distance between the second hinge point and the sliding member. The sliding member has a driving force downward along the axis. When the bottom plate support frame 50 is manually lifted, the bottom plate support frame 50 rotates counterclockwise around the second hinge point, and the acting force of the telescopic assembly 60 on the bottom plate support frame 50 is also a counterclockwise torsional force. Therefore, the telescopic assembly 60 can provide assistance when the second end of the bottom plate support frame 50 folds towards the sliding member, so that it is easier for the operator to lift the sliding hopper device 100. When the second end of the bottom plate support frame 50 approaches the sliding member, the first distance is greater than the second distance. When the bottom plate support frame 50 folds, the second end of the bottom plate support frame 50 approaches the sliding member, and the distance between the first hinge point and the sliding member is greater than the distance between the second hinge point and the sliding member. When the sliding hopper device 100 unfolds, the bottom plate support frame 50 rotates clockwise around the second hinge point, and the sliding member has a driving force downward along the axis, which can assist the bottom plate support frame 50 to rotate clockwise and unfold.

[0073] In one embodiment, as Figure 2As shown, the bottom plate support frame 50 includes: a bottom frame portion 51; and a plurality of rotating portions 52 arranged on a side of the bottom frame portion 51 close to the sliding member, wherein one end of the rotating portion 52 away from the bottom frame portion 51 is hinged to the vertical plate support frame 40 and the hinge point is the second hinge point; and a power-assisting support portion 53, wherein the other end of the power-assisting support portion 53 is hinged to the telescopic assembly 60 and the hinge point is the first hinge point; wherein the plurality of rotating portions 52 and the power-assisting support portion 53 are arranged alternately and spaced along the length direction of the bottom frame portion 51. The bottom frame portion 51 of the bottom plate support frame 50 can be used to install the bottom plate, and can install a plurality of rotating portions 52 and a plurality of power-assisting support portions 53. The rotating portion 52 is hinged to the vertical plate support frame 40, and when the bottom plate support frame 50 rotates, the second hinge point at which the rotating portion 52 is hinged to the vertical plate support frame 40 remains stationary. The power-assisting support portion 53 is hinged to the telescopic assembly 60, and the telescopic assembly 60 can transmit its own driving force to the base frame portion 51 through the power-assisting support portion 53, so that the upward second end of the base support frame 50 can be folded toward the sliding member or unfolded away from the sliding member.

[0074] In one embodiment, Figure 2 As shown, the rotating part 52 includes a first hinge section 522 and a first welding section 521. One end of the first welding section 521 is welded to the top surface of the bottom frame part 51, and the other end of the first hinge section 522 is connected to the first welding section 521 in an arc transition. The first hinge section 522 is bent and extended toward the vertical plate support frame 40 and is hinged to the vertical plate support frame 40. The first hinge section 522 and the first welding section 521 form an avoidance space. The first welding section 521 of the rotating part 52 is welded to the top surface of the bottom plate support frame 50. The first hinge section 522 of the rotating part 52 is hinged to the vertical plate support frame 40. When the bottom plate support frame 50 rotates, the first hinge section 522 of the rotating part 52 rotates around the second hinge point. The first hinge section 522 and the first welding section 521 form an avoidance space, which can avoid the components on the vertical plate support frame 40 to prevent the risk of interference.

[0075] In one embodiment, Figure 2 As shown, the power-assisting support portion 53 includes a second hinged section 532 and a second welding section 531, one end of the second welding section 531 is welded to the bottom surface and the side surface of the bottom frame portion 51, and the other end of the second hinged section 532 is connected to the second welding section 531 in an arc transition, and the second hinged section 532 is bent and extended in the direction of the telescopic assembly 60 and is hinged to the telescopic assembly 60. The second welding section 531 is welded to the bottom surface and the side surface of the bottom frame portion 51, which can make the connection between the power-assisting support portion 53 and the bottom frame portion 51 more stable. The second hinged section 532 is bent and extended in the direction of the telescopic assembly 60, so that the driving force of the telescopic assembly 60 can be more stably transmitted to the bottom plate support frame 50, the force-bearing structure is better, and the power-assisting of the telescopic assembly 60 is more stable.

[0076] In one embodiment,Figure 2 As shown, the bottom plate support frame 50 further includes: side baffles 54. The side baffles 54 extend along the width direction of the bottom plate support frame 50 on the chassis part 51. The bottom end of the side baffle 54 is connected to the chassis part 51, and one end of the side baffle 54 close to the vertical plate support frame 40 is hinged to the vertical plate support frame 40. Among them, the hinge point between the support frame and the vertical plate support frame 40 is the third hinge point, and the third hinge point is located on the extension line of the second hinge point extending along the length direction of the bottom plate support frame 50. The side baffle 54 can prevent the objects on the bottom plate from falling from the sliding hopper device 100, and thus can prevent the occurrence of high-altitude throwing accidents. And the bottom end of the side baffle 54 is connected to the chassis part 51, and one end of the side baffle 54 close to the vertical plate support frame 40 is hinged to the vertical plate support frame 40, which further strengthens the connection strength between the bottom plate support frame 50 and the vertical plate support frame 40 and prevents the risk of mechanical damage during long-term use. The hinge point between the support frame and the vertical plate support frame 40 is the third hinge point, and the third hinge point is located on the extension line of the second hinge point extending along the length direction of the bottom plate support frame 50. Therefore, the second hinge point and the third hinge point rotate synchronously when the bottom plate support frame 50 rotates. The side baffle 54 strengthens the connection structure between the bottom plate support frame 50 and the vertical plate support frame 40, and also strengthens the structural strength of the bottom plate support frame 50 itself, preventing mechanical failures that may occur during long-term use of the bottom plate support frame 50.

[0077] In a specific embodiment, as Figure 5 shown, it is the force-bearing structure diagram of the sliding hopper device 100 provided by the embodiment of the present invention. The included angle between the bottom plate support frame 50 and the vertical plate support frame 40 is α, the included angle between the connection line of the second hinge point and the third hinge point and the connection line of the second focus and the total center of gravity is β, and the distance between the second hinge point and the third hinge point is l 推 , the distance between the second hinge point and the total center of gravity is l 总 , the included angle between the connection line of the second focus and the total center of gravity and the connection line of the second hinge point and the first hinge point is γ, and the distance between the second hinge point and the first hinge point is l 气 , the total gravity is F 总 , the driving force of the telescopic component 60 is F 气 , the upward thrust of the manual at the third hinge point is F 推 . According to the force-bearing relationship and the force balance formula, when the distance between the first hinge point and the sliding part is less than the distance between the second hinge point and the sliding part, the driving force of the telescopic component 60 can be obtained according to formula (1):

[0078]

[0079] When the distance between the first hinge point and the sliding part is greater than the distance between the second hinge point and the sliding part, the driving force of the telescopic component 60 can be obtained according to formula (2):

[0080]

[0081] According to the above formula (1) and formula (2), a telescopic component 60 of corresponding specifications can be selected to meet the power assistance requirements.

[0082] In one embodiment, Figure 3 As shown, the sliding bucket device 100 also includes: a fence member 70, which is hinged to the side of the bottom frame part 51 away from the sliding member and is arranged parallel to the vertical plate support frame 40, and the hinge point between the bottom plate support frame 50 and the fence member 70 is the fourth hinge point; the bottom plate member (not shown in the figure) is arranged on the bottom plate support frame 50, and the side baffle 54, the bottom plate member and the fence member 70 together enclose a storage space. The fence member 70 is arranged on the side of the bottom frame part 51 and the principle sliding member, and can be used to install the side plate to prevent the personnel on the sliding bucket device 100 from accidentally falling from a high altitude. The hinge section between the bottom plate support frame 50 and the fence member 70 is the fourth hinge point, and the fourth hinge point is at the farthest distance between the bottom plate support frame 50 and the second hinge point. Applying a force at the fourth hinge point can make it easier to swing the second end of the bottom plate support frame 50 toward or away from the sliding member. The storage space can accommodate personnel for the sliding bucket device 100, so that the personnel can be transported up and down along the sliding member through the sliding bucket device 100.

[0083] In one embodiment, Figure 1 As shown, the sliding bucket device 100 also includes: a fixed ladder 80, one end of the fixed ladder 80 is connected to the vertical plate support frame 40, and the other end of the fixed ladder 80 extends upward in the direction of the sliding member and can be abutted with the top limit of the sliding member. The fixed ladder 80 is used to connect the accommodation space with the external emergency area. The sliding bucket device 100 is usually installed on a sliding member such as a guide rail, and is used to transport people in distress and rescue personnel. The fixed ladder 80 is arranged to extend toward the sliding member, so that people in distress and rescue personnel can enter and exit the accommodation space in the sliding bucket device 100 through the fixed ladder 80. The fixed ladder 80 is connected to the vertical plate support frame 40, and the connection is more stable and the failure rate is lower. In a specific embodiment, the fixed ladder 80 is detachably connected to the vertical plate support frame 40. When the sliding bucket device 100 is installed, the skeleton of the sliding bucket device 100 can be spliced ​​first, and then the fixed ladder 80 is installed on the vertical plate support frame 40. The installation is stable, and the detachable connection structure can be disassembled and replaced when there is a fault in the fixed ladder 80, which is convenient for maintenance. In another specific embodiment, the fixed ladder 80 is welded to the vertical plate support frame 40. Compared with the detachable connection structure, the welded structure is more stable and has a lower failure rate.

[0084] In one embodiment, the telescopic assembly 60 includes: a compression cylinder 61 with one end open and the other end hinged to the bottom plate support frame 50; a telescopic rod 62 with one end inserted into the compression cylinder 61 and forming a storage space for storing the gas medium to be compressed with the compression cylinder 61, and the other end of the telescopic rod 62 hinged to the vertical plate support frame 40. The telescopic assembly 60 includes the compression cylinder 61 and the telescopic rod 62, and the compression cylinder 61 and the telescopic rod 62 form a storage space capable of storing the gas medium. When the telescopic assembly 60 is installed in the sliding bucket device 100, the storage space is filled with the compressed gas medium so that the telescopic assembly 60 can always have a driving force to extend axially outward to assist the second end of the bottom plate support frame 50 to swing towards or away from the sliding member.

[0085] In a specific embodiment, the telescopic assembly 60 is a gas spring with a compressed gas medium and can always apply an outward acting force in the axial direction.

[0086] In one embodiment, as Figure 6 shown, it is a schematic structural diagram of the braking mechanism 10 of the sliding bucket device 100 provided according to an embodiment of the present invention; as Figure 7 shown, it is a schematic structural diagram of the cooperation between the braking mechanism 10 and the lifting mechanism 20 of the sliding bucket device 100 provided according to an embodiment of the present invention; as Figure 8 shown, it is Figure 7 a partial enlarged schematic diagram of component A in. The sliding bucket device 100 is a device capable of sliding on a sliding member for transporting personnel and materials. In the embodiment of the present invention, the sliding bucket device 100 includes a braking mechanism 10 and a lifting mechanism 20. The braking mechanism 10 of the sliding bucket device 100 includes: a mounting bracket 11; a braking shaft 12 rotatably arranged on the mounting bracket 11 and drivingly connected to the lifting mechanism 20; a braking member 13 mounted on the outer periphery of the braking shaft 12 and used to perform a braking operation after the braking shaft 12 rotates; an emergency assembly 14 drivingly connected to the braking shaft 12 and used to drive the braking shaft 12 to rotate in an accidental state, where the accidental state is a state where the lifting mechanism 20 is disconnected from the braking shaft 12, or the sliding bucket device 100 is stuck in motion, or the lifting speed of the lifting mechanism 20 exceeds a preset speed range.

[0087] The mounting bracket 11 can be mounted on the sliding bucket device 100 and can be used to mount other components of the braking mechanism 10. The braking shaft 12 is rotatably arranged on the mounting bracket 11. The lifting mechanism 20 can drive the braking shaft 12 to move up and down so that the sliding bucket device 100 slides on the sliding member. The braking member 13 is mounted on the outer periphery of the braking shaft 12. After the braking shaft 12 rotates, it can drive the braking member 13 to frictionally brake with the sliding member. The emergency component 14 can pull the braking shaft 12 when the sliding bucket device 100 is in an accidental state, so that the braking shaft 12 rotates. The rotation of the braking shaft 12 can drive the braking member 13 to work, so that the braking member 13 frictionally brakes with the sliding member. In addition, one side of the sliding member is the braking member 13, and the other side is a clamping plate member (not shown in the figure) on the braking mechanism. When the braking member 13 frictionally contacts the sliding member, the clamping plate member can clamp and brake the sliding member together with the braking member 13. When the lifting mechanism 20 is disconnected from the braking shaft 12, the lifting mechanism 20 cannot continue to drive the braking shaft 12 to move up and down, and the sliding bucket device 100 will fall downward due to gravity. At this time, the emergency component 14 can pull the braking shaft 12 and drive the braking member 13 to brake. In addition, the jamming of the sliding bucket device 100 and the lifting speed of the lifting mechanism 20 exceeding the preset speed range both belong to the scope of accidental states, and the braking mechanism 10 needs to be activated to prevent safety accidents of the sliding bucket device 100.

[0088] By adopting the above braking mechanism 10 for the sliding bucket device 100, it is possible to automatically perform a braking operation when the sliding bucket device 100 is in an accidental state, and the mechanical transmission between the components of the braking mechanism 10 is simple, the torque transmission is stable, and the braking mechanism 10 can stably perform the braking operation.

[0089] In one embodiment, as Figure 2As shown, the sliding bucket device 100 is slidably engaged with the sliding member. The emergency component 14 includes a connecting crank 141 and an elastic member 142. The first end of the connecting crank 141 is sleeved on the outer periphery of the brake shaft 12 and is coaxially and drivingly connected to the brake shaft 12, and the second end is pivotally connected to the elastic member 142. In an accidental state, the elastic tensile force of the elastic member 142 drives the connecting crank 141 to rotate, so that the braking mechanism 10 enters the braking state, and the braking member 13 frictionally brakes with the sliding member. When the sliding bucket device 100 is in an accidental state, the acting force between the hoisting mechanism 20 and the brake shaft 12 is disconnected, and the connecting crank 141 can drive the brake shaft 12 to rotate under the action of the elastic member, so that the brake wheel frictionally brakes with the sliding member. The emergency component 14 of the present application includes an elastic member 142, and the elastic member 142 has a tensile force. When the sliding bucket device 100 is in a normal state, the brake shaft 12 is subjected to the acting force of the hoisting mechanism 20, and the elastic member 142 cannot pull the connecting crank 141. When the sliding bucket device 100 is in an accidental state (such as the hoisting rope is disconnected), there is no acting force or a small acting force between the brake shaft 12 and the hoisting mechanism 20, and the elastic member 142 can pull the connecting crank 141 and drive the brake shaft 12 and the braking member 13 to rotate, so that the braking member 13 can frictionally brake with the sliding member. With the above braking mechanism 10, when the sliding bucket device 100 is in an accidental state, the braking mechanism 10 can automatically perform the braking operation to prevent the sliding bucket device 100 from falling risk.

[0090] In the first specific embodiment, the accidental state is that the hoisting rope is disconnected. When the hoisting rope is disconnected, there is no acting force between the brake shaft 12 and the hoisting mechanism 20, and the elastic member 142 can pull the connecting crank 141 and drive the brake shaft 12 and the braking member 13 to rotate, so that the braking member 13 can brake the sliding bucket device 100.

[0091] In the second specific embodiment, the accidental state is that the sliding bucket device 100 is stuck in motion. When the sliding bucket device 100 is descending, because the hoisting mechanism 20 is connected to the braking mechanism through a flexible component, the hoisting rope, when the sliding bucket device 100 is stuck in motion, there is no acting force between the hoisting rope and the braking mechanism 10, and the elastic member 142 can pull the connecting crank 141 and drive the brake shaft 12 and the braking member 13 to rotate, so that the braking member 13 can brake the sliding bucket device 100.

[0092] In the third specific embodiment, the unexpected state is that the hoisting speed of the hoisting mechanism 20 exceeds the preset speed range. When the hoisting speed exceeds the preset speed range, the sliding bucket device 100 cannot move smoothly, and the braking mechanism 20 performs a braking operation. For example, during the descent of the sliding bucket device 100, when the acceleration of the hoisting mechanism 20 is too large, the acting force between the sliding bucket device 100 and the hoisting mechanism 20 is small or there is no acting force. The elastic member 142 can pull the connecting crank 141 and drive the brake shaft 12 and the brake member 13 to rotate, so that the brake member 13 can brake the sliding bucket device 100.

[0093] In addition, there are other unexpected situations that can cause the elastic member 142 to pull the connecting crank 141, which will not be listed one by one here. For those of ordinary skill in the art, the specific meanings of the above unexpected situations in the present utility model can be understood according to specific circumstances.

[0094] In one embodiment, as Figure 7 shown, the hoisting mechanism 20 includes a connection block 21 for drivingly connecting with the brake shaft 12. When the hoisting mechanism 20 is operating normally, the hoisting mechanism 20 drives the connection block 21 to rotate upward. The connection block 21 drives the braking mechanism 10 to maintain its normal state, and the brake member 13 is separated from the sliding member. The connection block 21 of the hoisting mechanism 20 is drivingly connected with the brake shaft 12. When the hoisting mechanism 20 is operating normally, the hoisting mechanism 20 transmits an upward tensile force. The connection block 21 can transmit a torsional force opposite to the acting force of the connecting crank 141 to the brake shaft 12 under the action of the upward tensile force, so that the brake shaft 12 remains stationary. When the brake shaft 12 does not rotate, the brake member 13 is separated from the sliding member, and the sliding bucket device 100 can slide up and down along the sliding member.

[0095] In one embodiment, as Figure 6 shown, the brake shaft 12 includes a first brake section 121, a connection section 122, and a second brake section 123 that are coaxially connected in sequence. The connection block 21 is sleeved on the outer periphery of the connection section 122, and brake members 13 are sleeved on the outer peripheries of both the first brake section 121 and the second brake section 123. The first brake section 121 and the second brake section 123 are coaxially connected to both sides of the connection section 122. When the hoisting mechanism 20 pulls the brake shaft 12, the position where the acting force is applied is at the central position of the brake shaft 12, which can enable the hoisting sliding bucket device 100 to slide up and down more smoothly. Brake members 13 are sleeved on both the first brake section 121 and the second brake section 123. When a braking operation needs to be performed, the brake members 13 on the first brake section 121 and the second brake section 123 simultaneously frictionally brake with the sliding member, which can make the braking of the sliding bucket device 100 more stable.

[0096] In one embodiment, as Figure 7 and Figure 8As shown, the sliding bucket device 100 includes a mounting frame 30. The brake shaft 12 passes through the mounting frame 30. The brake mechanism 10 further includes: a first limiting rod 15, with both ends of the first limiting rod 15 connected to the mounting frame 30 respectively. The first limiting rod 15 is arranged parallel and at intervals above the brake shaft 12 and is used to limit the upward rotation angle of the connecting block 21; a second limiting rod 16, with both ends of the second limiting rod 16 connected to the mounting frame 30 respectively. The second limiting rod 16 is arranged parallel and at intervals below the brake shaft 12 and is used to limit the downward rotation angle of the connecting block 21. The connecting block 21 can rotate upward under the action of the lifting mechanism 20. When the elastic member 142 pulls the brake shaft 12 to rotate, the connecting block 21 will be forced to rotate downward. However, the force conditions of the connecting block 21 are different, and the swinging areas of the connecting block 21 are different. When the connecting block 21 swings towards the sliding member, it is easy to generate frictional collision with the sliding member. Therefore, it is necessary to limit the swinging angle of the connecting block 21. The brake mechanism 10 of the embodiment of the present invention includes a first limiting rod 15 and a second limiting rod 16. The first limiting rod 15 and the second limiting rod 16 can respectively limit the upward rotation angle and the downward rotation angle of the connecting block 21, preventing the connecting block 21 from being forced to interfere and collide with the sliding member.

[0097] In one embodiment, as Figure 8 shown, the mounting bracket 11 includes: a mounting seat 111, which is detachably mounted in the mounting frame 30. Two mounting seats 111 are respectively mounted at both ends of the brake shaft 12 and are provided with a mounting space for accommodating the brake member 13; an end cover baffle 112, which is arranged on the side end face of the mounting seat 111 and is rotatably connected to the brake shaft 12. The mounting seat 111 can be used to mount the brake member 13, and the end cover baffle 112 can be used to mount the first brake section 121 or the second brake section 123 of the brake member 13. When installing the brake mechanism 10, the mounting seat 111 and the end cover baffle 112 can be installed first, and then the brake member 13 is installed in the mounting space inside the mounting seat 111. The first brake section 121 or the second brake section 123 passes through the brake member 13 and is rotatably connected to the end cover baffle 112 to complete the installation of the brake module. Subsequently, the connection section 122 of the brake module is coaxially connected to the brake shaft 12 to complete the assembly of the brake mechanism 10. By adopting the above brake mechanism 10, the brake mechanism 10 can be assembled modularly, simplifying the assembly steps of the brake mechanism 10 and improving the assembly efficiency.

[0098] In one embodiment, as Figure 8As shown, the radial cross section of the brake member 13 is a fan-shaped structure, and the outer periphery of the brake member 13 is provided with an arc-shaped friction end surface protruding outward (not shown in the figure). When the brake member 13 rotates, the friction end surface of the brake member 13 faces the sliding member, and the sliding bucket device 100 is braked to stop. In a specific embodiment, the friction end surface is arranged at the large end of the fan-shaped structure, and when the large end faces the sliding member, the brake member 13 and the sliding member rub against each other; when the small end faces the sliding member, the brake member 13 and the sliding member are spaced apart from each other.

[0099] In one embodiment, the number of brake members 13 is multiple, and the multiple brake members 13 are arranged in parallel and spaced apart along the axial direction of the brake shaft 12, and the multiple brake members 13 are symmetrically distributed with the center of the brake shaft 12 as the symmetry point. The sliding bucket device 100 can usually move on multiple sliding members, and the guide rails on different sliding members have different widths. Therefore, the utility model is provided with multiple brake members 13 so that the brake members 13 can cooperate with guide rails of different widths to make the braking more timely and efficient. Among them, the brake member 13 can be selected as a brake cam, a brake block or other structural forms.

[0100] By using the brake mechanism 10 of the above-mentioned sliding bucket device 100, when the sliding bucket device 100 is in an unexpected state, the elastic member 142 on the brake mechanism 10 can pull the connecting crank 141 to rotate in the direction of the elastic member 142, so that the brake shaft 12 rotates, and the rotation of the brake shaft 12 can drive the brake member 13 to rotate. The outer periphery of the brake member 13 is provided with a friction end surface protruding outward. The friction between the friction end surface and the sliding member can brake the sliding bucket device 100 to prevent the sliding bucket device 100 from falling at a high altitude. By using the brake mechanism 10 of the above-mentioned sliding bucket device 100, the torque transmission between the various components is stable, the movement speed is fast, and the sliding bucket device 100 can be stably braked.

[0101] The above-mentioned sliding bucket device 100 can help the second end of the bottom plate support frame 50 of the sliding bucket device 100 to swing toward or away from the sliding member, so that the sliding bucket device 100 is easy to fold or unfold. In addition, the fixed ladder 80 of the sliding bucket device 100 can be firmly connected to the vertical plate support frame 40, which is convenient for transporting people in distress and emergency rescue personnel.

[0102] In one embodiment, an emergency device is provided, comprising: a sliding member; and the above-mentioned sliding bucket device 100.

[0103] In a specific embodiment, the emergency equipment is a fire truck, the ladder is a fire ladder, and the fire ladder includes a guide rail and a sliding bucket device 100 arranged on the guide rail.
