Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of welding fixtures for fire-fighting turntables, specifically relating to a deformation-resistant clamping fixture for welding fire-fighting turntables. Background Technology
[0002] The fire turntable is the core operating device of aerial fire trucks (such as ladder fire trucks and aerial platform fire trucks). It is mainly used to carry firefighters, fire extinguishing equipment, and rescue equipment to complete key tasks such as fire extinguishing, rescue, and material transportation at high altitudes. It serves as an "aerial combat platform" for emergency rescue in complex scenarios such as high-rise buildings and large factories. Its core structure consists of four main modules: a rotating mechanism, a boom, a working platform, and a hydraulic system. The rotating mechanism can achieve 360° continuous rotation, ensuring no blind spots in the working area. The multi-section telescopic boom is hydraulically driven and can lift the platform to a height of 30-100 meters (the specific height varies depending on the model). The working platform is equipped with guardrails, an anti-slip floor, and an emergency descent device, and can accommodate 2-5 firefighters at the same time, as well as carrying equipment such as water cannons, ladders, and rescue stretchers. The hydraulic system provides stable power for the overall movement, ensuring the accuracy and safety of high-altitude operations. During welding, the fire turntable needs to be clamped and fixed using anti-deformation clamping fixtures.
[0003] Currently, existing anti-deformation clamping fixtures for welding fire-fighting turntables typically use hydraulic cylinders to press down the clamping blocks to clamp the fire-fighting turntable during use. However, the clamping position of traditional anti-deformation clamping fixtures for welding fire-fighting turntables is often fixed and cannot be adjusted according to actual conditions. Therefore, it may be difficult to clamp and fix fire-fighting turntables of different specifications, thereby reducing the stability of the fixture in clamping and welding fire-fighting turntables. Utility Model Content
[0004] The purpose of this utility model is to provide an anti-deformation clamping fixture for welding fire-fighting turntables. This addresses the problem that existing anti-deformation clamping fixtures for welding fire-fighting turntables typically use hydraulic cylinders to press down the clamping blocks to achieve welding clamping. However, the clamping position of traditional anti-deformation clamping fixtures for fire-fighting turntable welding is often fixed and cannot be adjusted according to actual conditions. Therefore, it may be difficult to clamp and fix fire-fighting turntables of different specifications, thus reducing the stability of the fixture in clamping and welding fire-fighting turntables.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a deformation-resistant clamping fixture for welding fire-fighting turntables, comprising a base, two fixed frames fixedly connected to the top of the base, a connecting seat fixedly connected to the top of the two fixed frames, a motor installed at one end of the connecting seat, a bidirectional lead screw connected to the output end of the motor, two threaded connecting blocks threadedly connected to the outer wall of the bidirectional lead screw, a movable seat fixedly connected to the bottom of the two threaded connecting blocks, a hydraulic cylinder installed at the bottom of the movable seat, and a clamping block connected to the output end of the hydraulic cylinder.
[0006] As a preferred embodiment of the anti-deformation clamping fixture for welding fire-fighting turntables according to this utility model, the end of the bidirectional lead screw away from the motor is connected to the connecting seat through a bearing to form a rotating connection structure.
[0007] As a preferred embodiment of the anti-deformation clamping fixture for welding fire-fighting turntables according to this utility model, the tops of the two threaded connecting blocks are fixedly connected with guide sliders, and the interior of the connecting seat is equipped with guide slide rails.
[0008] As a preferred embodiment of the anti-deformation clamping fixture for welding fire-fighting turntables according to this utility model, the two threaded connecting blocks can form a sliding connection structure with the connecting seat through guide sliders and guide rails.
[0009] As a preferred embodiment of the anti-deformation clamping fixture for welding fire-fighting turntables according to this utility model, the top of the base is provided with a collection groove, the inner side of the collection groove is equipped with a fixing frame, the inner side of the fixing frame is provided with multiple bearing crossbars at equal intervals, the outer wall of the base is provided with a chip discharge port, and the bottom inner side of the base is provided with a chip guide block.
[0010] As a preferred embodiment of the anti-deformation clamping fixture for welding fire-fighting turntables according to this utility model, the cross-section of the chip guide block is triangular.
[0011] As a preferred embodiment of the present invention, a deformation-resistant clamping fixture for welding fire-fighting turntables is provided, wherein the chip guide block is located directly below multiple load-bearing crossbars.
[0012] Compared with the prior art, the beneficial effects of this utility model are: The motor drives the bidirectional lead screw to rotate, which allows the two threaded connecting blocks on the outer wall to move towards or opposite each other along the guide rail under the action of the guide slider. As the two threaded connecting blocks move, the movable seat at the bottom will drive the two hydraulic cylinders to move together. Thus, the distance between the two hydraulic cylinders can be adjusted through the above structure, so that the anti-deformation clamping fixture can clamp fire-fighting turntables of different sizes to prevent deformation and improve stability.
[0013] By using a collection trough, a fixed frame, supporting crossbars, a chip discharge port, and a chip guide block, when the fire-fighting turntable is placed on multiple supporting crossbars for clamping and welding, the welding slag falling on the base will pass through the gaps between the multiple supporting crossbars and fall onto the chip guide block. Then, the chip guide block on the top slope can guide the welding slag to the chip discharge port. The staff only needs to place a collection box below the chip discharge port to collect the falling welding slag, thereby improving the convenience of welding slag collection.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-4 The present invention provides the following technical solution: a deformation-resistant clamping fixture for welding fire-fighting turntables, comprising a base 1, two fixed brackets 2 fixedly connected to the top of the base 1, a connecting seat 3 fixedly connected to the top of the two fixed brackets 2, a motor 4 installed at one end of the connecting seat 3, a bidirectional lead screw 5 connected to the output end of the motor 4, two threaded connecting blocks 6 threadedly connected to the outer wall of the bidirectional lead screw 5, a movable seat 7 fixedly connected to the bottom of the two threaded connecting blocks 6, a hydraulic cylinder 8 installed at the bottom of the movable seat 7, and a clamping block 9 connected to the output end of the hydraulic cylinder 8.
[0018] Preferably, the end of the bidirectional lead screw 5 away from the motor 4 is connected to the connecting seat 3 through a bearing to form a rotating connection structure. The top of the two threaded connecting blocks 6 is fixedly connected to the guide slider 10. The connecting seat 3 is equipped with a guide slide rail 11. The two threaded connecting blocks 6 can form a sliding connection structure with the connecting seat 3 through the guide slider 10 and the guide slide rail 11.
[0019] In practical use, the motor 4 drives the bidirectional lead screw 5 to rotate, so that the two threaded connecting blocks 6 connected by the outer wall can move towards each other or in opposite directions along the guide slide rail 11 under the action of the guide slider 10. As the two threaded connecting blocks 6 move, the movable seat 7 at the bottom will drive the two oil cylinders 8 to move together. Thus, the distance between the two oil cylinders 8 can be adjusted through the above structure, so that the anti-deformation clamping fixture can clamp fire-fighting turntables of different sizes to prevent deformation and improve stability. It should be noted that when the motor 4 drives the bidirectional lead screw 5 to rotate clockwise, the two threaded connecting blocks 6 will drive the two oil cylinders 8 at the bottom to move in opposite directions. Conversely, when the motor 4 drives the bidirectional lead screw 5 to rotate counterclockwise, the two threaded connecting blocks 6 will drive the two oil cylinders 8 at the bottom to move in opposite directions.
[0020] Preferably, the base 1 has a collection groove 12 on its top, a fixing frame 13 is installed on the inner side of the collection groove 12, and multiple bearing crossbars 14 are evenly distributed on the inner side of the fixing frame 13. The outer wall of the base 1 has a chip discharge port 15, and a chip guide block 16 is provided on the inner bottom of the base 1. The cross section of the chip guide block 16 is triangular, and the chip guide block 16 is located directly below the multiple bearing crossbars 14.
[0021] In practical use, through the arrangement of the collection trough 12, the fixing frame 13, the bearing crossbar 14, the chip discharge port 15, and the chip guide block 16, when the fire-fighting turntable is placed on multiple bearing crossbars 14 for clamping and welding, the welding slag falling on the base 1 will pass through the gaps between the multiple bearing crossbars 14 and fall onto the chip guide block 16. Then, the chip guide block 16 on the top slope can guide the welding slag to the chip discharge port 15. The staff only needs to place a collection box under the chip discharge port 15 to collect the falling welding slag, thereby improving the convenience of welding slag collection.
[0022] Working principle: First, the fire-fighting turntable is placed on multiple supporting crossbars 14. Then, according to the size of the fire-fighting turntable, the motor 4 drives the double-acting screw 5 to rotate, causing the two threaded connecting blocks 6 on their outer walls to move towards or opposite each other along the guide rail 11 under the action of the guide slider 10. As the two threaded connecting blocks 6 move, the movable seat 7 at its bottom will drive the two hydraulic cylinders 8 to move together. Thus, the distance between the two hydraulic cylinders 8 can be adjusted through the above structure. After adjustment, by operating the two hydraulic cylinders 8, the clamping block 9 is pressed down on the bottom. The fire-fighting turntable is clamped to prevent deformation during welding. Through the arrangement of the collection trough 12, fixing frame 13, bearing crossbar 14, chip discharge port 15 and chip guide block 16, when the fire-fighting turntable is placed on multiple bearing crossbars 14 for clamping and welding, the welding slag falling on the base 1 will pass through the gaps between the multiple bearing crossbars 14 and fall onto the chip guide block 16. Then, the chip guide block 16 on the top slope can guide the welding slag to the chip discharge port 15. The staff only needs to place a collection box under the chip discharge port 15 to collect the falling welding slag, thereby improving the convenience of welding slag collection.
[0023] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
