Working bucket and lifting machinery

Abstract

The present invention relates to the technical field of lifting machinery, and provides a working bucket and a lifting operation machinery. The working bucket includes: a bucket body, which is provided with a storage space; a guide structure, which is connected to the bottom of the bucket body away from the storage space and extends to the side of the bucket body; a support assembly, which is movably connected to the guide structure and can be switched between a working state and a storage state. In the working state, at least a portion of the support assembly extends out of the bottom of the bucket body, and in the storage state, the support assembly retracts into the bottom of the bucket body. The support assembly is provided with a support portion for mounting a stretcher. The stretcher can be arranged in the portion of the support assembly extending out of the bottom of the bucket body, so that the stretcher is located outside the storage space of the bucket body and close to the bottom of the bucket body, thereby enabling the stretcher to not occupy the storage space in the bucket body. In addition, the stretcher is close to the bottom of the bucket body and has a lower height, so there is no need to lift the injured person onto the guardrail. The lifting height is lower, which is more convenient for rescuers to lift and place the injured person, and can reduce the labor intensity of rescuers.

Description

Technical Field

[0001] The present invention relates to the technical field of lifting machinery, in particular to a working bucket and a lifting operation machinery. Background Art

[0002] Lifting machines are widely used in firefighting and aerial rescue operations. They typically consist of a boom and a bucket. The boom is attached to the vehicle's body, and the bucket is connected to the movable end of the boom. The boom drives the bucket, allowing firefighters to reach designated locations and conduct rescue operations.

[0003] The work bucket can also be used to transfer the injured. Those who are able to stand can stand inside the work bucket. However, injured individuals who are unable to stand require a stretcher. Because the work bucket is typically small and inconvenient for placing a stretcher, when a stretcher is needed, it is typically placed on the guardrail of the work bucket, supported by the guardrail and secured with straps.

[0004] While this method can effectively transfer the injured, the stretcher takes up a significant amount of space in the work bucket, making it difficult for rescuers to stand inside. This reduces the number of rescuers the bucket can accommodate, hinders collaboration between rescuers, increases labor intensity, and increases the risk of rescue. Furthermore, the guardrails are often too high, making it difficult for rescuers to lift or lower the injured. Summary of the Invention

[0005] The present invention provides a working bucket and a lifting operation machine, which are used to solve the defects in the prior art that a stretcher is set on the guardrail of the working bucket, occupies a large space in the working bucket, and is inconvenient for rescue personnel to lift and place the wounded. The present invention achieves the effect of reducing the space occupied by the stretcher in the working bucket and lowering the height to which rescue personnel lift the wounded.

[0006] The present invention provides a working bucket, comprising:

[0007] The bucket body is provided with a receiving space;

[0008] a guide structure connected to a side of the bottom of the bucket body away from the accommodating space, the guide structure extending toward the side of the bucket body;

[0009] A support assembly is movably connected to the guide structure and can be switched between a working state and a storage state. In the working state, at least a portion of the support assembly extends out from the bottom of the bucket body. In the storage state, the support assembly retracts into the bottom of the bucket body. The portion of the support assembly extending out from the bottom of the bucket body is provided with a support portion for mounting a stretcher.

[0010] According to a working bucket provided by the present invention, the support assembly includes a sliding portion, the sliding portion is slidably connected to the guide structure, the support portion is connected to the sliding portion, and the support portion is provided with a connecting structure for connecting to the stretcher.

[0011] A working bucket provided according to the present invention further includes a first driving mechanism, which connects the bucket body and the support assembly and is used to drive the support assembly to move.

[0012] According to a working bucket provided by the present invention, the working bucket further includes a second driving mechanism, wherein the sliding portion includes a first sliding seat and a second sliding seat that are slidably connected, and the relative movement direction of the first sliding seat and the second sliding seat is parallel to the guide structure, and the second driving mechanism is used to drive the first sliding seat and the second sliding seat to move relative to each other;

[0013] The first sliding seat and the second sliding seat are both slidably connected to the guide structure, the first sliding seat is connected to the first driving mechanism, and the second sliding seat is connected to the supporting portion.

[0014] According to a working bucket provided by the present invention, the support portion is rotatably connected to the sliding portion, and the support portion can be switched between a first state and a second state. In the first state, the length direction of the support portion is parallel to the guide structure, and in the second state, the length direction of the support portion is perpendicular to the guide structure.

[0015] According to a working bucket provided by the present invention, a hook is provided on the support portion, and a slot is provided on the sliding portion. The slot is arranged on the rotation path of the hook. When the support portion is in the first state, the hook is located at one end of the support portion close to the bucket body and engages with the slot.

[0016] The working bucket provided by the present invention further includes a connecting piece, which detachably connects the stretcher and the bucket body.

[0017] According to a working bucket provided by the present invention, the connecting member includes at least one of a pull rod, a pull rope and a binding rope.

[0018] According to a working bucket provided by the present invention, the supporting portion includes a first support and a second support, the first support is connected to the sliding portion, and the second support is rotatably connected or slidably connected to the first support so that the second support can be folded or telescopic relative to the first support.

[0019] The present invention also provides a lifting operation machine, comprising the working bucket as described above.

[0020] The work bucket provided by the present invention has a guide structure disposed on the side of the bottom of the bucket body, away from the storage space, and a support assembly movably connected to the guide structure. In the working state, at least a portion of the support assembly extends beyond the bottom of the bucket body. In the stowed state, the support assembly retracts into the bottom of the bucket body. Furthermore, the portion of the support assembly extending beyond the bucket body is provided with a support portion for mounting a stretcher. When a patient needs to be transferred, the support assembly can be switched to the working state, and a stretcher can be mounted on the support assembly, allowing the patient to be placed on the stretcher.

[0021] With such arrangement, when the support assembly moves along the guide structure and extends out from the bottom of the bucket body, the stretcher can be set at the part of the support assembly extending out from the bottom of the bucket body, so that the stretcher is located outside the accommodating space of the bucket body and close to the bottom of the bucket body, so that the stretcher does not occupy the accommodating space inside the bucket body and does not affect the rescuers standing in the bucket body. In addition, the stretcher is close to the bottom of the bucket body and has a lower height, so there is no need to lift the injured person onto the guardrail. The lifting and placing height is lower, which is more convenient for rescuers to lift and place the injured person, and can reduce the labor intensity of rescuers.

[0022] In addition, after the rescue is completed, the support assembly can be switched to the storage state, and the support assembly can be retracted to the bottom of the bucket body, which can reduce the space occupied by the support assembly on the working bucket and avoid the support assembly affecting the original function of the working bucket.

[0023] Since the lifting operation machine provided by the present invention includes the working bucket of the present invention, it also includes all the above advantages of the working bucket. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0043] The existing work bucket can be used to transfer the wounded. Those who are able to stand on their own can stand in the work bucket. However, those who are seriously injured and unable to stand need to be transferred and rescued using a stretcher. Since the space in the work bucket is usually small and not convenient for placing a stretcher, when a stretcher is needed for rescue, the stretcher is usually placed on the guardrail of the work bucket, supported by the guardrail, and then secured with straps. This method can effectively transfer the wounded, but the stretcher takes up a large space in the work bucket, making it inconvenient for rescuers to stand in the work bucket, reducing the number of rescuers that the work bucket can accommodate, making it difficult for rescuers to cooperate in lifting and lowering the injured, and increasing the rescuers' labor intensity. In addition, the guardrail is usually high, which also makes it difficult for rescuers to lift and lower the injured, resulting in a high labor intensity for rescuers when lifting and lowering the injured.

[0044] In order to solve the defects in the prior art that the stretcher is set on the guardrail of the work bucket, taking up a large space in the work bucket and having a high height that is inconvenient for rescuers to lift and place the wounded, and to achieve the effect of reducing the space occupied by the stretcher in the work bucket and lowering the height to which rescuers lift the wounded, a work bucket and a lifting operation machine are provided in an embodiment of the present invention.

[0045] The following combination Figures 1 to 12 The working bucket provided in the embodiment of the present invention is described.

[0046] Specifically, the working bucket includes a bucket body 1, a guide structure 4 and a support assembly.

[0047] The bucket body 1 is provided with a storage space for accommodating people and objects. For example, the bucket body 1 includes a base 101 and a guardrail 102. The guardrail 102 is arranged along the edge of the base 101, and the base 101 and the guardrail 102 enclose a storage space for accommodating people and objects. The guardrail 102 is provided with an entrance and exit for people to enter and exit, as well as a door for opening and closing the entrance and exit.

[0048] The guide structure 4 is connected to the side of the bottom of the bucket body 1 away from the storage space, and the guide structure 4 extends toward the side of the bucket body 1. The side of the bottom of the bucket body 1 away from the storage space refers to the side of the base 101 of the bucket body 1 away from the storage space, that is, below the base 101. The guide structure 4 extends toward the side of the bucket body 1, that is, the guide structure 4 extends toward one side of the bucket body 1. For example, the extension direction of the guide structure 4 can be the same as the direction of the entrance. Optionally, the guide structure 4 can be a guide rail or a guide groove. As shown in the figure, the number of guide rails or guide grooves is set to one pair.

[0049] The support assembly is movably connected to the guide structure 4. For example, the support assembly is provided with a slider for sliding connection with a pair of guide rails or a pair of guide grooves. Figures 1-6As shown, the support assembly can be switched between an operating state and a stowed state. In the operating state, at least a portion of the support assembly extends out of the bottom of the bucket body 1. In the stowed state, the support assembly is retracted into the bottom of the bucket body 1. The portion of the support assembly extending out of the bottom of the bucket body 1 is provided with a support portion 3 for mounting a stretcher 7.

[0050] In the working bucket provided in the embodiment of the present invention, when it is necessary to transfer a wounded person, the support assembly can be switched to the working state, and the stretcher 7 can be connected to the support assembly, so that the wounded person can be placed on the stretcher 7. In this arrangement, when the support assembly moves along the guide structure 4 and extends out of the bottom of the bucket body 1, the stretcher 7 can be arranged at the portion of the support assembly extending out of the bottom of the bucket body 1, so that the stretcher 7 is located outside the storage space of the bucket body 1 and close to the bottom of the bucket body 1, thereby enabling the stretcher 7 to not occupy the storage space inside the bucket body 1 and not affect the rescuers standing inside the bucket body 1. In addition, the stretcher 7 is close to the bottom of the bucket body 1 and has a lower height, so there is no need to lift the wounded person onto the guardrail 102. The lifting height is lower, which is more convenient for rescuers to lift and place the wounded person, and can reduce the rescuers' labor intensity.

[0051] In addition, after the rescue is completed, the stretcher 7 can be removed and the support assembly can be switched to the storage state. The support assembly is retracted to the bottom of the bucket body 1, which can reduce the space occupied by the support assembly on the working bucket and avoid the support assembly affecting the original function of the working bucket.

[0052] In some embodiments provided herein, the support assembly includes a sliding portion 2. The sliding portion 2 is slidably connected to a guide structure 4, and the support portion 3 is connected to the sliding portion 2. The support portion 3 is provided with a connecting structure for connecting to a stretcher 7. For example, the sliding portion 2 is provided with a slider that slidably engages with a pair of guide grooves or rails of the guide structure 4. For example, the connecting structure may include connecting holes or connecting posts. After the stretcher 7 is placed on the support assembly, it can be secured to the support portion 3 by passing a strap through the connecting holes or around the connecting posts. Of course, the connecting structure may also include a female buckle, which is provided on the support portion 3. The stretcher 7 is provided with a male buckle, which is provided on the support portion 3 and connected to the female buckle via the male buckle, thereby securing the stretcher 7 to the support portion 3. For example, the structure of the male and female buckles can refer to the buckle structure of a car seat belt.

[0053] In some embodiments provided herein, the working bucket further includes a first drive mechanism 5. This first drive mechanism 5 connects the bucket body 1 and the support assembly and is used to drive the support assembly to move. This arrangement allows the support assembly to switch between a working state and a stowed state via the first drive mechanism 5, making use more labor-saving and convenient.

[0054] In some embodiments provided herein, the first drive mechanism 5 is a hydraulic cylinder or a pneumatic cylinder. For example, the cylinder of the first drive mechanism 5 is rotatably connected to the bucket body 1, and the piston rod of the first drive mechanism 5 is rotatably connected to the sliding portion 2. When the first drive mechanism 5 is extended or retracted, it drives the sliding portion 2 to move along the guide structure 4. Using a hydraulic cylinder or a pneumatic cylinder as the first drive mechanism 5 simplifies the structure of the first drive mechanism 5 and enables the sliding portion 2 to be locked in either the operating or retracted state, thereby enhancing safety.

[0055] Of course, the first drive mechanism 5 is not limited to being configured as an oil cylinder or a pneumatic cylinder. For example, the first drive mechanism 5 can also be an electric cylinder. Alternatively, the first drive mechanism 5 can be an electric motor or a hydraulic motor that drives the sliding portion 2 along the guide structure 4 through a gear rack drive mechanism. Preferably, the electric motor and hydraulic motor are equipped with a braking function.

[0056] In some embodiments provided by the present invention, the working bucket further includes a second driving mechanism 6. The sliding portion 2 includes a first sliding seat 201 and a second sliding seat 202. The first sliding seat 201 and the second sliding seat 202 are slidably connected, and the relative movement direction of the first sliding seat 201 and the second sliding seat 202 is parallel to the guide structure 4. The second driving mechanism 6 is used to drive the first sliding seat 201 and the second sliding seat 202 to move relative to each other. The first sliding seat 201 and the second sliding seat 202 are both slidably connected to the guide structure 4, the first sliding seat 201 is connected to the first driving mechanism 5, and the second sliding seat 202 is connected to the support portion 3. Optionally, the two ends of the second driving mechanism 6 are respectively connected to the first sliding seat 201 and the second sliding seat 202, or the two ends of the second driving mechanism 6 are respectively connected to the bucket body 1 and the second sliding seat 202.

[0057] During use, when the support assembly needs to be switched to the working state, the first drive mechanism 5 drives the first sliding seat 201 to move laterally toward the working bucket, and the second drive mechanism 6 drives the second sliding seat 202 to move laterally toward the working bucket. When the support assembly needs to be switched to the storage state, the first drive mechanism 5 drives the first sliding seat 201 to move toward the bottom of the working bucket, and the second drive mechanism 6 drives the second sliding seat 202 to move toward the bottom of the working bucket.

[0058] like Figure 7 As shown, the first sliding seat 201 is driven by the first driving mechanism 5, and the second driving mechanism 6 drives the second sliding seat 202 to move relative to the first sliding seat 201. On the one hand, it can ensure that the second sliding seat 202 has a sufficient extension length so that the support part 3 on the second sliding seat 202 can sufficiently support the stretcher 7. At the same time, in the storage state, the second sliding drive belt support part 3 can be completely retracted to the bottom of the working bucket.

[0059] On the other hand, Figure 7 and Figure 8 As shown, when the second sliding seat 202 drives the support part 3 to extend out of the bottom of the working bucket, the second sliding seat 202 is connected to the guide structure 4 and the first sliding seat 201 respectively, that is, the first sliding seat 201 and the guide structure 4 jointly support the second sliding seat 202, thereby ensuring the stability and support rigidity of the second sliding seat 202, so that the second sliding seat 202 can provide a safer and more stable support effect for the support part 3. It can also be understood from another perspective, that is, the first sliding seat 201 and the second sliding seat 202 are considered as a whole, such as Figure 5 As shown, when the support assembly is in the storage state, the first sliding seat 201 shares the force of the second sliding seat 202, improving the force condition of the second sliding seat 202, so that the second sliding seat 202 can provide a safer and more stable support effect for the support part 3.

[0060] In some embodiments provided herein, the second drive mechanism 6 is a hydraulic cylinder or a pneumatic cylinder. For example, the cylinder body of the second drive mechanism 6 is rotatably connected to the first sliding seat 201, and the piston rod of the second drive mechanism 6 is rotatably connected to the second sliding seat 202. When the second drive mechanism 6 is extended or retracted, it can drive the second sliding seat 202 to move relative to the first sliding seat 201. By using a hydraulic cylinder or a pneumatic cylinder as the second drive mechanism 6, the structure of the second drive mechanism 6 is simplified, and the hydraulic cylinder or pneumatic cylinder can be used to lock the first sliding seat 201 and the second sliding seat 202 relative to each other, preventing relative movement between the first sliding seat 201 and the second sliding seat 202 when not needed, thereby improving safety.

[0061] Of course, the second drive mechanism 6 is not limited to being an oil cylinder or a pneumatic cylinder. For example, the second drive mechanism 6 can also be an electric cylinder. Alternatively, the second drive mechanism 6 can be an electric motor or a hydraulic motor that drives the first sliding seat 201 and the second sliding seat 202 to move relative to each other through a rack and pinion drive mechanism. Preferably, the electric motor and the hydraulic motor are equipped with a braking function.

[0062] like Figure 6-Figure 7 As shown, in some embodiments provided by the present invention, a guide rod 2011 is provided on the first sliding seat 201, and a guide cylinder 2021 is provided on the second sliding seat 202. The guide rod 2011 and the guide cylinder 2021 are both parallel to the guide structure 4, and the guide rod 2011 can slidably extend into the guide cylinder 2021 so that the guide rod 2011 and the guide cylinder 2021 can guide each other. With this arrangement, the first sliding seat 201 and the second sliding seat 202 can be slidably connected via the guide rod 2011 and the guide cylinder 2021 that are in sliding engagement.

[0063] In some embodiments provided by the present invention, the support portion 3 is rotatably connected to the sliding portion 2, and the support portion 3 can switch between a first state and a second state. Figure 12As shown, in the first state, the length direction of the support portion 3 is parallel to the guide structure 4, as shown in FIG. Figure 9 As shown, in the second state, the length direction of the support portion 3 is perpendicular to the guide structure 4. It should be noted that the length direction of the support portion 3 refers to the length direction of the stretcher 7 after the stretcher 7 is installed on the support portion 3.

[0064] When using the support portion 3, the state of the support portion 3 can be set according to actual needs. For example, when the support assembly is in the working state, the support portion 3 extends from the portion of the working bucket where the entrance and exit are located, and the connection between the support portion 3 and the sliding portion 2 is opposite the entrance and exit. When the support portion 3 is in the first state and is parallel to the guide structure 4, it can serve as a connecting bridge between the working bucket and the rescue point, allowing people in the working bucket to reach the rescue point by passing through the support portion 3. For another example, in a narrow space that is difficult for the working bucket to enter, the support portion 3 can be switched to the first state, allowing the support portion 3 to enter the narrow space, making it easier to lift and place the injured person on the stretcher 7 of the support portion 3. For another example, during the movement of the working bucket, the support portion 3 can be switched to the second state, allowing the stretcher 7 to be close to the working bucket, making it easier for rescuers in the working bucket to observe and care for the injured person. This also facilitates connecting the working bucket to the stretcher 7 using connectors, improving the stability and safety of the stretcher 7 and helping the working bucket avoid obstacles during operation.

[0065] In some embodiments provided herein, the support portion 3 can be rotatably connected to the sliding portion 2 via a rotating shaft. Specifically, for example, the rotating shaft can be fixed to the support portion 3, and the sliding portion 2 can be provided with a shaft hole for the rotating shaft to extend into and rotate. Optionally, a bearing can be provided in the shaft hole, and the rotating shaft extends into the inner ring of the bearing.

[0066] Optionally, the support portion 3 can be positioned using a positioning pin. Specifically, a through-hole is provided on the sliding portion 2, and a positioning hole is provided on the support portion 3. The positioning pin extends through the through-hole and into the positioning hole, thereby positioning the support portion 3. Two through-holes can be provided, and the positions of the two through-holes correspond to the two states of the support portion 3. For example, when the support portion 3 is rotated to the first state, the positioning hole is opposite to one of the two through-holes. When the support portion 3 is rotated to the second state, the positioning hole is opposite to the other of the two through-holes.

[0067] Optionally, the support portion 3 is driven for rotation by an electric motor or hydraulic motor. Specifically, the electric motor or hydraulic motor can be mounted on the sliding portion 2, with its output shaft connected to the support portion 3 via a coupling or gear transmission structure, thereby driving the support portion 3 to rotate. Alternatively, the electric motor or hydraulic motor can be mounted on the support portion 3, with its output shaft connected to the sliding portion 2. Optionally, the electric motor or hydraulic motor can be equipped with a braking function to prevent the support portion 3 from rotating when it is not needed.

[0068] like Figure 10-11 As shown, in some embodiments provided by the present invention, a hook 303 is provided on the support portion 3, and a slot 203 is provided on the sliding portion 2. The slot 203 is provided on the rotation path of the hook 303. When the support portion 3 is in the first state, the hook 303 is located at one end of the support portion 3 close to the bucket body 1, and the hook 303 is engaged with the slot 203. Figure 10 As shown, when the support part 3 is in the first state, the support part 3 can serve as a connecting bridge between the working bucket and the rescue point. When the rescuer on the working bucket steps on the end of the support part 3 away from the working bucket, the connection structure between the support part 3 and the sliding part 2 is subjected to greater force. By setting the hook 303 and the slot 203 to engage with each other, the load on the connection structure between the support part 3 and the sliding part 2 can be shared, thereby improving the stability of the support part 3 and avoiding damage to the connection structure between the support part 3 and the sliding part 2.

[0069] In some embodiments provided by the present invention, the working bucket further comprises a connecting piece, which detachably connects the stretcher 7 and the bucket body 1. Such an arrangement can improve the stability of the stretcher 7 during the movement of the working bucket.

[0070] Optionally, the connecting member includes at least one of a pull rod, a pull rope, and a binding rope. Specifically, while the working bucket is moving, the support portion 3 can be switched to the second state, bringing the stretcher 7 close to the side of the working bucket. The stretcher 7 can then be connected to the bucket body 1 using the pull rod, pull rope, or binding rope to improve the stability of the stretcher 7. The pull rod can be connected to the bucket body 1 and the stretcher 7 via hooks, respectively. Similarly, the pull rope can be connected to the bucket body 1 and the stretcher 7 via hooks. The binding rope can be used to tie the stretcher 7 to the side of the bucket body 1.

[0071] like Figures 1-6 As shown, in some embodiments provided by the present invention, the support portion 3 includes a first support 301 and a second support 302. The first support 301 is connected to the sliding portion 2, for example, the first support 301 is rotatably connected to the sliding portion 2. The second support 302 is rotatably connected or slidably connected to the first support 301, so that the second support 302 can be folded or extended relative to the first support 301.

[0072] With this arrangement, in the use state, the second support 302 can be expanded or extended relative to the first support 301, so that the support portion 3 can provide a larger support area for the stretcher 7, thereby more stably supporting the stretcher 7. In the storage state, the second support 302 can be folded or retracted relative to the first support 301 to reduce the area occupied by the support portion 3, making it easier to store.

[0073] Optionally, the second support 302 is hingedly connected to the first support 301 , or a guide rail or a guide groove is provided on the first support 301 , and the second support 302 is slidably connected to the guide rail or the guide groove on the first support 301 .

[0074] An embodiment of the present invention further provides a lifting operation machine.

[0075] Specifically, the aerial work machine includes the working bucket as described above.

[0076] It should be noted that the lifting operation machinery includes the working bucket as described above, and also includes all the advantages of the working bucket, which will not be repeated here.

[0077] It should also be noted that the aerial work machinery described in this application includes but is not limited to aerial work vehicles, aerial work vehicles or aerial fire trucks.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
