Description

Technical Field

[0001] This utility model relates to the technical field of construction transfer devices, specifically a transfer device for bridge and road construction that facilitates loading and unloading of materials. Background Technology

[0002] Roads are the foundation of urban development. Good roads can bring convenience to urban logistics and transportation. Roads are divided into surface roads and bridge roads. In the construction of bridge roads, the transfer of materials is a critical and frequent task. The materials used, such as pipes, steel, or rebar, need to be transported to the bridge for use in laying or assembly. However, traditional transfer devices have many inconveniences in the loading and unloading process. Workers need to firmly bind these materials before they can be lifted and transferred to the bridge by crane. Workers spend a lot of time binding them, and if they are not firmly bound, the materials are prone to falling, which greatly affects the efficiency and safety of construction and is not conducive to people's use. Utility Model Content

[0003] The purpose of this invention is to provide a transfer device for bridge and road construction that facilitates loading and unloading of materials, so as to solve the problem of low efficiency in material transfer and fixing mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a transfer device for bridge and road construction that facilitates loading and unloading of materials, comprising a frame, the outer surface of which is a frame design, and extension rods fixedly installed on both outer surfaces of the frame. A lifting clamp slider is slidably installed on the outer surface of the extension rods. A lifting strap is rotatably installed on the outer surface of the lifting clamp slider. A main clamping wheel is rotatably installed on the outer surface of one end of the lifting clamp slider. A gear and worm gear assembly is fixedly installed on the outer surface of one end of the lifting clamp slider, and the output end of the gear and worm gear assembly is rotatably connected to the lifting clamp slider. A worm wheel is rotatably installed inside the lifting clamp slider, and the worm wheel is connected to the main clamping wheel. The worm wheel meshes with the output end of the gear and worm gear assembly. A secondary clamping wheel is rotatably installed on the outer surface of one end of the lifting clamp slider, and a gap is left between the secondary clamping wheel and the main clamping wheel.

[0005] Preferably, a control box is fixedly installed on the outer surface of the frame, and the control box is connected to the gear and worm gear assembly. A lifting lug is rotatably installed on the outer surface of the frame, and a lifting cable is threaded through the inside of the lifting lug.

[0006] By adopting the above technical solution, the gear and worm gear assembly can be operated remotely or directly through the control box, and the lifting lugs facilitate the replacement of the lifting cable, making maintenance convenient and enabling remote operation.

[0007] Preferably, a rack is fixedly installed on the outer surface of the extension rod, and the outer surface of the rack engages with the lifting clamp slider.

[0008] By adopting the above technical solution, after the transfer device is lifted by the crane, the weight of the lifted material and the clamp slider allows the rack and clamp slider to be tightly engaged, so that the clamp slider will not move randomly due to shaking or other reasons during material transfer, thereby reducing the material falling due to the movement of the clamp slider.

[0009] Preferably, an installation block is fixedly installed on the outer surface of the end of the extension rod away from the frame, and the installation block is fixed to the extension rod with screws. The installation block engages with the rack. A steel cable assembly is inserted and installed on the outer surface of the installation block, and another steel cable assembly is inserted and fixed on the side surface of the frame. A turnbuckle assembly is inserted and installed between the two steel cable assemblies, and the outer surface of the turnbuckle assembly is in contact with the outer surface of the steel cable assembly.

[0010] By adopting the above technical solution, the mounting block can limit the movement of the lifting clip slider, so that even if the lifting clip slider slips during use, it will not detach from the extension rod and cause the material to fall. When the components on the lifting clip slider are damaged, the mounting block can be removed and the lifting clip slider can be removed and replaced. The use of steel cable assembly and turnbuckle assembly can improve the rigidity of the extension rod, and improve the stability and load-bearing capacity of the extension rod during use.

[0011] Preferably, the outer surface of the lifting clip slider is threaded with a bolt pin, which is inserted into one end of the sling. The end of the lifting clip slider away from the extension rod is inclined. Grooves are formed on both outer surfaces of the lifting clip slider, and the grooves of the lifting clip slider engage with the sling.

[0012] Using the above technical solution, the sling can be removed from the lifting clamp slider after the bolt pin is removed, which facilitates the replacement of damaged slings after long-term use. The inclined design of the lifting clamp slider allows the material to be automatically positioned and gathered after the sling is tightened, so that the material can be clamped more tightly and firmly. In addition, the grooves opened on the outer surface of both sides of the lifting clamp slider can also make the sling lock into the outer surface of the lifting clamp slider after tightening, so that the sling can be more firmly gathered and hugged to the material, and will not slide left and right.

[0013] Preferably, a ratchet is rotatably mounted on the outer surface of the clamping slider, and the ratchet is connected to the shaft of the auxiliary clamping wheel. A spring ratchet is rotatably mounted inside the clamping slider, and the spring ratchet engages with the ratchet. One end of the spring ratchet penetrates the outer surface of the clamping slider.

[0014] By employing the above technical solution, the use of ratchet and spring ratchet prevents the secondary clamping wheel from automatically retracting after rotation, reducing the likelihood of the sling failing to be clamped due to the rotation of the secondary clamping wheel.

[0015] Preferably, a stop bar is fixedly installed on the outer surface of the lifting clip slider, and a protrusion is provided on the outer surface of one end of the stop bar. The outer surface of the stop bar is inserted into the outer surface of one end of the lifting strap, and the outer surface of the lifting strap is in contact with the outer surface of the stop bar.

[0016] By adopting the above technical solution, the sling can be wound into the stop bar after tightening, and one end of the sling can be locked into the stop bar, so that the material held by the sling will not fall suddenly after it is loosened, thus further improving the safety during the transportation process.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this bridge and road construction transfer device facilitates loading and unloading of materials.

[0018] 1. When using the device, simply lower the frame and thread the sling through the material to be transferred. Then, activate the gear and worm gear assembly to drive the meshing worm wheel to rotate, allowing the main clamping wheel to rotate. After that, insert the sling and drive the auxiliary clamping wheel to rotate, so that the auxiliary clamping wheel and the main clamping wheel can tighten the material, making the material stick tightly to the outer surface of the sling slider for quick fixation. This reduces the time spent fixing and binding the material. The self-locking property of the gear and worm gear assembly and worm wheel prevents the sling from loosening and causing the material to fall, improving the convenience and efficiency of use.

[0019] 2. By using the rack fixed to the outer surface of the extension rod, when the lifting clip slider needs to be moved to change its position relative to another lifting clip slider, the lifting clip slider only needs to be slightly lifted to disengage from the rack. Then the lifting clip slider can be moved to adjust its position. The engagement between the lifting clip slider and the rack can further improve the stability of the lifting clip slider when moving and lifting materials, so that the lifting clip slider will not slide on the extension rod due to shaking or other reasons when the material is lifted, thus improving the stability when transferring materials.

[0020] 3. By fixing the mounting block to the extension rod, the chance of the lifting clamp slider slipping off the extension rod can be prevented. The fixing of the mounting block to the rack further improves the stability of the mounting block. At the same time, the use and fixing of the steel cable assembly and turnbuckle assembly can further improve the connection strength between the extension rod and the frame, making the load-bearing capacity of the extension rod higher and more secure, while preventing the danger caused by the lifting clamp slider falling off.

[0021] 4. By engaging the ratchet and spring ratchet, the sling is prevented from rotating in the opposite direction and slipping after it is inserted between the main clamp wheel and the auxiliary clamp wheel. This prevents the material secured by the clamp slider and the sling from falling, further improving the safety of the lifted material. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a transfer device for bridge and road construction that facilitates loading and unloading of materials, including a frame 1. The outer surface of the frame 1 is a frame design, and extension rods 3 are fixedly installed on both sides of the outer surface of the frame 1. A control box 4 is fixedly installed on the outer surface of the frame 1, and the control box 4 is connected to a gear and worm gear assembly 14. A lifting lug 2 is rotatably installed on the outer surface of the frame 1, and a lifting cable is threaded through the inside of the lifting lug 2.

[0031] First, when using it, simply pass the lifting cable through the lifting lug 2 and connect it to the crane. Then, the crane can be used to lift or lower the frame 1 to move it to a different position.

[0032] A rack 5 is fixedly installed on the outer surface of the extension rod 3, and the outer surface of the rack 5 engages with the lifting clip slider 9. The lifting clip slider 9 is slidably installed on the outer surface of the extension rod 3. An installation block 7 is fixedly installed on the outer surface of the end of the extension rod 3 away from the frame 1, and the installation block 7 is fixed to the extension rod 3 with screws. The installation block 7 engages with the rack 5. A steel cable assembly 6 is inserted and installed on the outer surface of the installation block 7, and another steel cable assembly 6 is inserted and fixed on the side surface of the frame 1. A turnbuckle assembly 8 is inserted and installed between the two steel cable assemblies 6, and the outer surface of the turnbuckle assembly 8 is in contact with the outer surface of the steel cable assembly 6.

[0033] Secondly, by engaging the mounting block 7 with the rack 5, and tightening and fixing the steel cable assembly 6 and the turnbuckle assembly 8, the steel cable assembly 6 and the turnbuckle assembly 8 can be adjusted, and the extension rod 3 can be made more secure. This allows the transfer device to lift more materials and bear greater weight, while preventing the materials from slipping due to shaking when lifted, thus improving the stability and reliability of the transfer device when transferring materials.

[0034] A lifting strap 13 is rotatably mounted on the outer surface of the lifting clamp slider 9. A main clamping wheel 10 is rotatably mounted on the outer surface of one end of the lifting clamp slider 9. A gear and worm gear assembly 14 is fixedly mounted on the outer surface of one end of the lifting clamp slider 9, and the output end of the gear and worm gear assembly 14 is rotatably connected to the lifting clamp slider 9. A worm wheel 15 is rotatably mounted inside the lifting clamp slider 9, and the worm wheel 15 is connected to the main clamping wheel 10. The worm wheel 15 meshes with the output end of the gear and worm gear assembly 14. A secondary clamping wheel 12 is rotatably mounted on the outer surface of one end of the lifting clamp slider 9, and there is a gap between the secondary clamping wheel 12 and the main clamping wheel 10. A ratchet 16 is rotatably mounted on the outer surface of the lifting clamp slider 9, and the ratchet 16 is connected to the rotating shaft of the secondary clamping wheel 12. A spring ratchet 17 is rotatably mounted inside the lifting clamp slider 9, and the spring ratchet 17 engages with the ratchet 16. One end of the spring ratchet 17 penetrates the outer surface of the lifting clamp slider 9.

[0035] Then, the frame 1 can be lowered and the position between the lifting clip sliders 9 can be adjusted according to the material to be lifted. At this time, simply lift the lifting clip sliders 9 slightly or let them contact the ground to disengage them from the rack 5, thereby changing the position of the lifting clip sliders 9 on the extension rod 3 so that they are in the optimal position for binding the material. Then, the lifting strap 13 can be passed under the material, and the gear and worm gear assembly 14 can be activated through the control box 4. The gear and worm gear assembly 14 can drive the meshing worm wheel 15, which in turn drives the main clamping wheel 10 to rotate. With the use of the auxiliary clamping wheel 12 and the self-locking property of the gear and worm gear assembly 14 and the worm wheel 15, the main clamping wheel 10 and the auxiliary clamping wheel 12 can tightly clamp the lifting strap 13, allowing the lifting strap 13 to retract and clamp the material to be fixed, improving the firmness and efficiency of fixing the material and enhancing the practicality of the transfer device when fixing the material.

[0036] The outer surface of the lifting clip slider 9 is threaded with a bolt pin 11, which is inserted into one end of the sling 13. The end of the lifting clip slider 9 away from the extension rod 3 is designed to be inclined. Grooves are provided on both sides of the outer surface of the lifting clip slider 9, and the grooves of the lifting clip slider 9 are engaged with the sling 13. A stop rod 18 is fixedly installed on the outer surface of the lifting clip slider 9, and a protrusion is provided on the outer surface of one end of the stop rod 18. The outer surface of the stop rod 18 is inserted into the outer surface of one end of the sling 13, and the outer surface of the sling 13 is in contact with the outer surface of the stop rod 18.

[0037] The sling 13 can be fixed or replaced using bolt pin 11. When the sling 13 is placed between the main clamping wheel 10 and the auxiliary clamping wheel 12, the auxiliary clamping wheel 12 will rotate together with the sling 13. At this time, the ratchet 16 will also rotate. The ratchet 17 and the ratchet 16 are engaged to prevent the auxiliary clamping wheel 12 from rotating in the opposite direction, making the sling 13 more secure after tightening. After the sling 13 is tightened, the other end of the sling 13 is inserted into the stop bar 18 to further improve the sling 13's firmness after fixing the material. Even if the main clamping wheel 10 and the auxiliary clamping wheel 12 slip accidentally, the sling 13 will not loosen directly, further improving the overall firmness and safety of the transfer device when transporting materials.

[0038] Working principle: The hoisting cable is passed through the lifting lug 2 and connected to the crane to move the transfer device. The transfer device can then be hoisted above the material. The position of the lifting clamp slider 9 on the extension rod 3 is then adjusted. The gear and worm gear assembly 14 is then slowly rotated via the control box 4, causing the sling 13 to pass under the material and be inserted between the main clamp wheel 10 and the auxiliary clamp wheel 12. This tightens the sling 13, quickly securing the transferred material. After securing the material, the sling 13 is wrapped around the stop rod 18 for further fixation. The crane then lifts the transfer device and the material and places them on the bridge road. The sling 13 is then removed from the stop rod 18, and the worker manually rotates the spring ratchet 17 to disengage it from the ratchet 16. The gear and worm gear assembly 14 is then rotated in the opposite direction to release the sling 13, allowing the material to be lowered. This completes the fixing, moving, and releasing of the transferred material.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
