Description

Technical Field

[0001] This utility model relates to the field of fire truck technology, and in particular to a fire operation platform, a fire truck body structure, and a fire truck. Background Technology

[0002] In the field of fire emergency rescue, the way fire truck equipment is secured plays a crucial role in rescue efficiency and equipment management. Currently, the conventional securing methods for most fire truck equipment fall into three categories: horizontal pull-out trays, vertical pull-out trays, and vertical rotating brackets.

[0003] Horizontal pull-out trays place equipment on trays that can be pulled out horizontally. In actual use, firefighters need to manually pull out the tray to retrieve the required equipment. The operation is entirely manual, and in emergency rescue situations, firefighters need to spend extra time and energy operating the tray, affecting the rapid deployment of rescue operations. Vertical pull-out trays, while utilizing the vertical space of the vehicle and increasing space utilization to some extent, require firefighters to pull the tray vertically upwards or downwards to store and retrieve equipment, resulting in low automation and difficulty in meeting the needs of efficient rescue. Vertical rotating racks secure equipment by hanging it on a vertically rotating frame. This method requires manually rotating the rack to locate the required equipment, making the operation cumbersome.

[0004] With the increasing complexity and diversification of fire rescue missions, the requirements for equipment securing devices on fire trucks are becoming more stringent. Existing conventional securing methods, due to their manual operation and low degree of automation, have gradually become factors restricting the improvement of fire rescue efficiency. Therefore, this utility model provides a fire-fighting operation platform. Utility Model Content

[0049] Figure 1 is a structural schematic diagram of the fire operation platform provided by the embodiments of the present application (the installation platform is in a folded state). Figure 2 is Figure 1 is an enlarged view of A part in Figure 3 is a structural schematic diagram of the fire operation platform provided by the embodiments of the present application (the installation platform is in an unfolded state). Figure 4 is Figure 3 is an enlarged view of B part in

[0050] Referring to Figures 1 to 4 , the embodiments of the present application provide a fire operation platform, which can be applied to a fire truck and the like for installing corresponding equipment. The fire operation platform 100 comprises a base 10, an installation platform 20 and a driving assembly 40.

[0051] The base 10 is adapted to be mounted to a compartment main body 200 of a fire truck compartment structure, and the base 10 can adopt high-strength aluminum alloy, which can withstand greater weight and impact force. When mounted to the fire truck compartment structure, a mounting interface convenient for assembly can be designed, such as a bolt connection seat with reinforcing ribs, to ensure the stability of the base 10 during vehicle driving.

[0052] The mounting platform 20 is connected with the base 10 through the hinged assembly 30, and the mounting platform 20 is suitable for fixing fire-fighting equipment. The mounting platform 20 can be provided with corresponding mounting positions for different types and sizes of fire-fighting equipment. For example, the fire extinguisher, the fire hose, the spray gun and other fire-fighting equipment can be fixed flexibly by using slidable clamps and telescopic straps, and the equipment can be adjusted conveniently when it is needed to be taken quickly.

[0053] The driving assembly 40 comprises a linear driving part 41 and a transmission part 42. The linear driving part 41 is arranged on the base 10, one end of the transmission part 42 is hinged with the linear driving part 41, and the other end of the transmission part 42 is hinged with the mounting platform 20. When the transmission part 42 drives the mounting platform 20 to move under the driving of the linear driving part 41, the mounting platform 20 rotates by 90 degrees along a first axis and continues to rotate by 90 degrees along a second axis, so that the mounting platform 20 is switched from the folded state to the unfolded state. The first axis and the second axis are arranged at an included angle, that is, the first axis and the second axis are not parallel, and the first axis and the second axis can be perpendicular to each other, which is equivalent to that the mounting platform 20 can be flipped in the vertical and horizontal directions. In this way, the fire-fighting operation platform 100 is in the folded state when not in use, which can improve the space utilization rate; and when in use, the fire-fighting operation platform 100 can be unfolded quickly, which can improve the efficiency of the fire-fighting operation.

[0054] It can be understood that the fire-fighting operation platform 100 provided by the utility model, the mounting platform 20 is connected with the base 10 through the hinged assembly 30, the driving assembly 40 comprises a linear driving part 41 and a transmission part 42, the linear driving part 41 is arranged on the base 10, one end of the transmission part 42 is hinged with the linear driving part 41, and the other end of the transmission part 42 is hinged with the mounting platform 20. When the transmission part 42 drives the mounting platform 20 to move under the driving of the linear driving part 41, the mounting platform 20 rotates by 90 degrees along a first axis and continues to rotate by 90 degrees along a second axis, so that the mounting platform 20 is switched from the folded state to the unfolded state. The first axis and the second axis are arranged at an included angle, that is, the first axis and the second axis are not parallel, and the first axis and the second axis can be perpendicular to each other, which is equivalent to that the mounting platform 20 can be flipped in the vertical and horizontal directions. In this way, the fire-fighting operation platform 100 is in the folded state when not in use, which can improve the space utilization rate; and when in use, the fire-fighting operation platform 100 can be unfolded quickly, which can improve the efficiency of the fire-fighting operation.

[0055] That is, when the mounting platform 20 is in the folded state, the space occupied by the mounting platform 20 can be effectively reduced. This is very important for fire trucks with strict space requirements, because fire trucks need to carry various fire-fighting equipment, facilities and accommodate fire-fighting personnel. Through such a design, more necessary facilities can be reasonably arranged in the limited vehicle compartment space, and the space utilization rate of the fire truck can be improved.

[0056] When the mounting platform 20 needs to be unfolded at the fire scene, the linear driving part 41 drives the mounting platform 20 to move through the transmission part 42, so that the mounting platform 20 can be quickly switched from the folded state to the unfolded state. Manual operation of the mounting platform 20 is avoided, and the automation degree can be improved.

[0057] Since the installation platform 20 can accurately reach the unfolded state through rotation of the specific axis, the time and effort of the firefighters to manually adjust the installation platform 20 are reduced. In the case of an emergency fire rescue, the installation platform 20 can be quickly unfolded, so that the fire-fighting equipment can be immediately put into use, thereby improving the efficiency of the entire fire-fighting operation.

[0058] In addition, through rotation along the mutually perpendicular axes, the installation platform 20 has a stable movement track during movement. This helps to reduce stress concentration and shaking due to irregular movement, reduces the impact on the transmission component 42 and the hinge assembly 30, prolongs the service life of the corresponding components, and also improves the stability of the installation platform 20 during unfolding and use.

[0059] With reference to Figure 2 and Figure 4 In some embodiments of the present application, the hinge assembly 30 includes a first hinge 31, a hinge shaft 32 and a second hinge 33, the first hinge 31 is fixed to the base 10, the second hinge 33 is fixed to the installation platform 20, and the first hinge 31 and the second hinge 33 are connected through the hinge shaft 32.

[0060] When the transmission component 42 drives the installation platform 20 to move under the drive of the linear drive component 41, the second hinge 33 is flipped 120 degrees relative to the first hinge 31, so that the installation platform 20 is switched from the folded state to the unfolded state.

[0061] The present application rationally designs the angles of the corresponding hinges in the hinge assembly 30 between the base 10 and the installation platform 20, so that the installation platform 20 can realize rotation of a preset angle (such as 120 degrees) during flipping, thereby switching the installation platform 20 from the folded state to the unfolded state according to the installation space, and the installation platform 20 can be in the folded state when not in use, thereby improving space utilization; when in use, the installation platform 20 can be quickly unfolded, thereby improving the efficiency of the fire-fighting operation.

[0062] Figure 5 is an angle marking schematic view of the fire-fighting operation platform provided by the embodiments of the present application.

[0063] With reference to Figure 2 and Figure 4 , and with reference to Figure 5In some embodiments of the utility model, first articulated piece 31 includes first articulated section 311, second articulated section 312 and third articulated section 313 that are connected in sequence, first articulated section 311 is located at the side of base 10, and is kept parallel with base 10, second articulated section 312 is arranged with first articulated section 311 at an angle, third articulated section 313 extends in the direction away from second articulated section 312, and third articulated section 313 is arranged with second articulated section 312 at an angle, third articulated section 313 is connected with first articulated piece 31 through articulated shaft 32.

[0064] Second articulated piece 33 includes fourth articulated section 331 and fifth articulated section 332 that are connected with each other, fourth articulated section 331 is arranged with fifth articulated section 332 at an angle, fourth articulated section 331 is located at mounting platform 20, and is kept parallel with mounting platform 20, fifth articulated section 332 is connected with third articulated section 313 through articulated shaft 32, wherein the angle between fourth articulated section 331 and fifth articulated section 332 is complementary to the angle between second articulated section 312 and first articulated section 311.

[0065] Correspondingly, the angle between first articulated section 311 and second articulated section 312 is designed as a specific value, which is assumed as α, and the angle range of α is 120 degrees to 130 degrees, in other words, the angle of α can be 120 degrees, 125 degrees or 130 degrees, that is, the angle of α can be any degree number between 120 degrees and 130 degrees.

[0066] The angle between second articulated section 312 and third articulated section 313 is designed as a specific value, which is assumed as β, and the angle range of β is 90 degrees to 135 degrees, in other words, the angle of β can be 90 degrees, can be 135 degrees, or can be any degree number between 90 degrees and 135 degrees.

[0067] Since the angle between fourth articulated section 331 and fifth articulated section 332 is complementary to the angle between second articulated section 312 and first articulated section 311, the sum of the angle γ between fourth articulated section 331 and fifth articulated section 332 and the angle α is 180 degrees, that is, the angle range of γ is 50 degrees to 60 degrees, in other words, the angle of γ can be 50 degrees, 55 degrees or 60 degrees, that is, the angle of γ can be any degree number between 50 degrees and 60 degrees.

[0068] When the transmission component 42 drives the mounting platform 20 to move under the driving of the linear driving component 41, the second articulated piece 33 rotates 120 degrees relative to the first articulated piece 31 around the articulated shaft 32, and the mounting platform 20 can realize 90 degrees of rotation in the vertical direction and the horizontal direction respectively.

[0069] Continuing to refer to Figure 1 And Figure 3In some embodiments of the utility model, the base 10 is provided with a mounting portion 11, the mounting portion 11 extends along one side of the base 10, and the first hinge member 31 is fixed to the mounting portion 11; the mounting platform 20 is provided with a mounting groove 21 corresponding to the shape of the mounting portion 11, and the second hinge member 33 is fixed to the groove wall of the mounting groove 21.

[0070] When the mounting platform 20 is in the unfolded state, the mounting portion 11 is clamped in the mounting groove 21, and the surface of the mounting portion 11 is parallel to the mounting platform 20.

[0071] In other words, during the conversion of the mounting platform 20 from the folded state to the unfolded state, the mounting portion 11 cooperates with the mounting groove 21 to play a guiding role, ensuring the accuracy of the movement trajectory of the mounting platform 20. At the same time, a limiting protrusion and a limiting groove can be arranged on the contact surface of the mounting portion 11 and the mounting groove 21. For example, limiting protrusions are arranged on both sides of the mounting portion 11, and limiting grooves are arranged at the corresponding positions of the mounting groove 21. The cooperation between the mounting portion 11 and the mounting groove 21 is like a mortise and tenon structure, which can withstand the weight of the fire-fighting equipment and external forces generated during the fire-fighting operation.

[0072] When the mounting platform 20 is unfolded to the appropriate position, the limiting protrusion and the limiting groove cooperate with each other to position the mounting platform 20 in the unfolded state, preventing over-expansion or under-expansion. When the mounting platform 20 is in the unfolded state, the surface of the mounting portion 11 is parallel to the mounting platform 20, which enhances the flatness of the mounting platform 20 in the unfolded state.

[0073] Continuing to refer to Figure 1 and Figure 3 In some embodiments of the utility model, the linear driving component 41 includes a driving mechanism, a lead screw 413, and a sliding block 414. The lead screw 413 is arranged on the base 10 through a bearing seat, the sliding block 414 is threadedly connected with the lead screw 413, the driving mechanism is fixed to the base 10 and is in transmission connection with the lead screw 413, and one end of the transmission component 42 is hingedly connected with the sliding block 414.

[0074] The stroke range of the lead screw 413 is 60mm to 64mm.

[0075] Further, the driving mechanism includes a driving member 411 and a transmission member 412. The driving member 411 is fixed to the base 10, the transmission member 412 is fixed to the lead screw 413, and the driving member 411 drives the transmission member 412 to move, so as to drive the lead screw 413 to rotate.

[0076] The driving member 411 can be a motor, a driving gear is connected to the output shaft of the motor through a key, the transmission member 412 can be a transmission gear, and the transmission gear is in meshing connection with the driving gear. The transmission component 42 includes a connecting rod, one end of the connecting rod is ball-hinged with the sliding block 414, and the other end of the connecting rod is ball-hinged with the mounting platform 20.

[0077] When the motor rotates forward or reversely to drive the driving gear connected to the output shaft of the motor to rotate correspondingly, the driving gear meshes with the transmission gear at the end of the lead screw, and the lead screw 413 rotates correspondingly. The sliding block 414 is limited by the sliding groove formed on the base 10, so that the sliding block 414 cannot rotate, but can only move in translation along the lead screw 413, thereby driving the connecting rod to move, to push the mounting platform 20 to continuously rotate in space around the hinge shaft 32, so as to finally make the mounting platform 20 continuously rotate by 90 degrees in two directions, to switch from the folded state to the unfolded state.

[0080] The compartment main body 200 can adopt high-strength aluminum alloy material, and the internal space of the compartment main body 200 can be divided into the fire equipment area 210 and the equipment storage area 220. The fire equipment area 210 is located at the rear part of the compartment and is used for installing large equipment such as fire pumps, water tanks and foam tanks.

[0081] The equipment storage area 220 is close to the cab, which facilitates firefighters to quickly take equipment. The equipment storage area 220 is used for storing various fire-fighting equipment such as fire extinguishers, fire hoses, spray guns and protective equipment, and the fire fighting operation platform 100 is arranged in the equipment storage area 220.
