Description

Technical Field

[0001] The utility model relates to the technical field of hoisting and clamping, and particularly relates to a clamping and fixing device for rod-shaped workpieces. Background Art

[0002] During the hoisting process of rod-shaped workpieces, the clamping and fixing device can tightly clamp the rod-shaped workpieces, effectively preventing the workpieces from falling due to factors such as wind force, vibration or improper operation during the hoisting process, and ensuring the safe progress of the hoisting operation.

[0003] If the weight distribution of the rod-shaped workpiece itself is uneven, or the goods are placed improperly during hoisting, resulting in one side being too heavy, it is easy to cause the workpiece to tilt during the hoisting process. The tilted workpiece may swing due to inertial force and collide with the operator, surrounding workers or other objects, resulting in personal injuries. The tilted workpiece may exert uneven forces on the lifting appliances and riggings, causing the lifting appliances and riggings to break or be damaged. The tilted workpiece may be squeezed, twisted or impacted during the hoisting process, resulting in deformation, cracking or surface damage of the workpiece.

[0004] Therefore, it is necessary to invent a clamping and fixing device for rod-shaped workpieces to solve the above problems. Summary of the Utility Model

[0005] To solve the deficiencies of the prior art, the purpose of the utility model is to provide a clamping and fixing device for rod-shaped workpieces, which solves the problem that during actual use or when the goods are placed improperly during hoisting, resulting in one side being too heavy, which is likely to cause the workpiece to tilt during the hoisting process. The tilted workpiece may swing due to inertial force and collide with the operator, surrounding workers or other objects, resulting in personal injuries.

[0006] To achieve the above objectives, the utility model adopts the following technical solutions:

[0007] A clamping and fixing device for rod-shaped workpieces includes a guide rail connected by a hoisting assembly. A plurality of clamping assemblies for clamping the rod are slidably arranged in the length direction of the guide rail. The clamping assembly includes a clamping block at its bottom end for clamping and fixing the rod. A push plate for controlling the clamping block is arranged inside the clamping assembly. One end of the clamping assembly is provided with a roller for driving the clamping assembly to slide along the length direction of the rod.

[0008] As a preferred solution of the utility model, the clamping assembly includes a slider sliding along the guide rail. A fixed frame is arranged at the bottom end of the slider. Guide grooves are formed on both side walls of the fixed frame. Both ends of the push plate can slide along the guide grooves.

[0009] As a preferred solution of the present utility model, a bottom support plate is provided at the bottom end of the fixed frame. Rotatable second clamping rods are provided on both sides below the guide groove of the bottom support plate, and the end of the second clamping rod is rotatably connected to a clamping block.

[0010] As a preferred solution of the present utility model, first clamping rods for driving the second clamping rods to swing synchronously are connected to both ends of the guide groove of the push plate. When the push plate slides downward, the first clamping rod presses the second clamping rod, so that the clamping block at the end of the second clamping rod clamps the rod.

[0011] As a preferred solution of the present utility model, an auxiliary mounting block is installed inside the fixed frame. A double-headed threaded rod with opposite rotation directions and located on both sides thereof is rotatably provided inside the auxiliary mounting block.

Specific implementation mode

[0021] The present utility model will be further described below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0022] The present utility model provides a rod-shaped workpiece clamping and fixing device as shown in Figures 1-4 which includes a guide rail 2 connected by a hoisting component. A plurality of clamping components 3 for clamping a rod 1 are slidably arranged in the length direction of the guide rail 2. The clamping component 3 includes a clamping block 11 at its bottom end for clamping and fixing the rod 1. A push plate 8 for controlling the clamping block 11 is arranged inside the clamping component 3. One end of the clamping component 3 is provided with a roller 18 for driving the clamping component 3 to slide along the length direction of the rod 1. At least three clamping components 3 are provided, and the clamping component 3 located in the middle is in a fixed state to prevent the rod 1 from sliding synchronously with the clamping component 3, resulting in fixing failure.

[0023] The clamping component 3 includes a slider 4 sliding along the guide rail 2. A fixed frame 5 is arranged at the bottom end of the slider 4. Guide grooves 9 are opened on both side walls of the fixed frame 5. Both ends of the push plate 8 can slide along the guide grooves 9. The arrangement of the guide grooves 9 is used to control the sliding direction of the push plate 8 to prevent its deviation, resulting in the failure of the clamping block 11 to close and affecting the clamping and fixing effects.

[0024] A bottom support plate 10 is arranged at the bottom end of the fixed frame 5. Rotatable second clamping rods 7 are arranged on both sides below the guide grooves 9 of the bottom support plate 10. The end of the second clamping rod 7 is rotatably connected to the clamping block 11. The contact surface between the clamping block 11 and the rod 1 is made of a damping block to ensure the friction force while avoiding scratching the workpiece.

[0025] The push plate 8 is connected with a first clamping rod 6 for driving the second clamping rod 7 to swing synchronously at both ends of the guiding groove 9. When the push plate 8 slides downward, the first clamping rod 6 presses the second clamping rod 7, so that the clamping block 11 at the end of the second clamping rod 7 clamps the rod 1.

[0026] An auxiliary mounting block 12 is installed inside the fixed frame 5. A double-headed threaded rod 19 with opposite rotation directions and located on both sides thereof is rotatably arranged inside the auxiliary mounting block 12. The upper half of the double-headed threaded rod 19 is threadedly connected with a pressing plate 13 that can slide longitudinally. One end of the pressing plate 13 extends to the top of the push plate 8. While lifting and sliding the sliding guiding frame 16, the double-headed threaded rod 19 will drive the pressing plate 13 to press down, achieving the effect that while the roller 18 disengages from the rod 1, the clamping block 11 clamps and fixes the rod 1.

[0027] The lower half of the double-headed threaded rod 19 is threadedly connected with a guiding plate 20. The bottom end of the guiding plate 20 is connected with a sliding guiding frame 16. A roller 18 is rotatably arranged at the bottom of the sliding guiding frame 16. A second rotating motor 17 for controlling the rotation of the roller 18 is sleeved outside the sliding guiding frame 16. By independently setting the second rotating motor 17 to control the rotation of the roller 18, the purpose of driving the clamping assembly 3 to slide is achieved. The roller 18 is arranged below, which is convenient for workers to use the device to clamp the rod 1. At the same time, the guiding and positioning of the roller 18 can achieve the centering effect, ensuring accurate clamping of the rod 1.

[0028] A gear set 14 that meshes with each other is arranged at the bottom end of the slider 4. One of the gears is sleeved on the top end of the double-headed threaded rod 19. A first rotating motor 15 for controlling the rotation of the gear set 14 is detachably installed on the outer side wall of the auxiliary mounting block 12. Arranging the gear set 14 at the bottom of the slider 4 can reduce the production and installation difficulty of the device and ensure the transmission effect of the double-headed threaded rod 19 at the same time.

[0029] In the present utility model, in the face of the problem that the hoisted rod 1 may be inclined on one side, by arranging a plurality of clamping assemblies 3 that can slide on the guide rail 2, the purpose of adjusting the center of gravity of the rod 1 is achieved. A plurality of clamping assemblies 3 are arranged. During the hoisting and moving process, if one side is inclined, the other clamping assemblies 3 remain in the clamping state. The clamping assembly 3 on the inclined side loosens by rotating the double-headed threaded rod 19. At the same time, the sliding guiding frame 16 and the roller 18 slide downward under the action of the double-headed threaded rod 19 to contact the rod 1. By rotating the roller 18, the position of the clamping assembly 3 on the guide rail 2 is adjusted, changing the force application points of the hoisting assembly and the guide rail 2, achieving the control of the center of gravity, thereby reducing or solving the problem of the inclination of one side of the rod 1 and avoiding the occurrence of potential safety hazards.

[0030] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
