Its working characteristics are intermittent movement, that is, the corresponding mechanisms of material collection, transportation, unloading and other actions work alternately in one working cycle. The development and use of cranes in the market are becoming more and more extensive. Cranes are assembled from a variety of structural parts. Crane structural parts refer to some components that constitute the main structure of the crane. They jointly support the function of the crane and ensure its stability and safety. When processing existing crane structural parts, due to assembly requirements, it is necessary to use a bending device to bend the crane structural parts.

[0021] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods. Example

[0022] like Figure 1-Figure 5 As shown, a crane structure bending device includes: a bending table 1 and a clamping assembly, an L-shaped bending mold 101 installed on the top of the bending table 1, a fixed block 2 installed on one side of the top of the bending table 1, and a clamping assembly arranged on one side of the outer end of the fixed block 2, the clamping assembly includes: a clamping block 201, a movable push frame 202, a mounting block 203, an electric push rod 204 and a through hole 205.

[0023] Among them, a clamping block 201 is provided on one side of the L-shaped bending mold 101, a movable push frame 202 is provided on the top of the clamping block 201, a mounting block 203 is fixedly installed between the movable push frame 202 and the clamping block 201 by bolts, an electric push rod 204 is provided at the outer end of the fixed block 2, a through hole 205 is opened on the inner side of the fixed block 2, and one end of the electric push rod 204 passes through the through hole 205 and is fixedly connected to the movable push frame 202.

[0024] When bending the crane structure, the crane structure is placed on the bending table 1, and the crane structure is placed close to the outer end of the L-shaped bending mold 101. At this time, the electric push rod 204 is started to pass through the through hole 205 and push the movable push frame 202 to move toward the L-shaped bending mold 101, so that the movable push frame 202 drives the clamping block 201 to move to the other side of the crane structure. The crane structure is clamped and fixed by the clamping block 201 and the L-shaped bending mold 101. After the electric push rod 204 pushes the movable push frame 202 and the clamping block 201 to move their positions, The movable push frame 202 and the clamping block 201 are placed against the crane structure to prevent the crane structure from loosening. After the crane structure is bent, the electric push rod 204 is started to drive the movable push frame 202 and the clamping block 201 to move to the left, so that the clamping block 201 is removed from the outer end of the crane structure, and the limit fixation of the crane structure is released to achieve the purpose of rapid disassembly and assembly, solve the problem that the bolt installation method of the clamp is cumbersome and cannot be quickly disassembled, and the bolts are easily damaged due to slipping when loosening and tightening for a long time, thereby improving the efficiency of the bending work of the crane structure.

[0025] The movable push frame 202 is made of solid metal material. The movable push frame 202 is heavy and has good center of gravity stability. It is not easy to loosen when the crane structure is limited and fixed.

[0026] Among them, a limit plate a3 is fixedly installed on one side of the fixed block 2, and a lateral pushing cylinder 301 is installed inside the limit plate a3. One end of the lateral pushing cylinder 301 is connected to a telescopic rod a302, and one end of the telescopic rod a302 is fixedly installed with a lateral bending push plate 303. After the crane structure is clamped and fixed by the clamping block 201 and the L-shaped bending mold 101, the lateral pushing cylinder 301 is started to drive the telescopic rod a302 to move toward the direction of the crane structure, so that the telescopic rod a302 pushes the lateral bending push plate 303 to connect with the crane structure. When the protruding part of the crane structure is touched, the transverse bending push plate 303 is continuously pushed and subjected to force, and the crane structure is bent toward the L-shaped bending mold 101. After the crane structure is bent transversely at a certain angle, the crane structure will become an arc shape and face the longitudinal bending push plate 403, and align with the longitudinal bending push plate 403. At this time, the transverse pushing cylinder 301 is started to drive the telescopic rod a302 to retract, driving the transverse bending push plate 303 to move back to its original position, thereby not affecting the working use of the longitudinal bending push plate 403.

[0027] Among them, a limit plate b4 is fixedly installed on one side of the top of the bending table 1 close to the transverse bending push plate 303, and a longitudinal pushing cylinder 401 is installed on the inner side of the limit plate b4, and one end of the longitudinal pushing cylinder 401 is connected to a telescopic rod b402, and one end of the telescopic rod b402 is fixedly installed with a longitudinal bending push plate 403. When the crane structure is bent at a certain angle, the crane structure will become an arc shape and face the longitudinal bending push plate 403. When aligned with the longitudinal bending push plate 403, the longitudinal pushing cylinder 401 is started to drive the telescopic rod b402 to move in the direction of the bent crane structure, so that the telescopic rod b402 pushes the longitudinal bending push plate 403 to contact the crane structure after the arc is bent, and the longitudinal bending push plate 403 is continuously pushed and subjected to force, so that the crane structure after the arc is pushed to fully fit with the L-shaped bending mold 101, so that the crane structure is bent into an L shape, and then the bending work of the crane structure is completed.

[0028] Among them, a control panel is fixedly installed on one side of the bottom of the bending table 1, and a power cord is installed at the bottom of the control panel. The electric push rod 204, the horizontal pushing cylinder 301 and the longitudinal pushing cylinder 401 are connected to the control panel through electric wires. The length of the power cord is 2 meters, and a plug is installed at the other end of the power cord, which can be inserted into an indoor socket to connect to the power supply, so that the control panel, the electric push rod 204, the horizontal pushing cylinder 301 and the longitudinal pushing cylinder 401 can be powered on and used normally. The electric push rod 204, the horizontal pushing cylinder 301 and the longitudinal pushing cylinder 401 can be controlled to start and stop through the control panel, and the control procedures involved in the utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art. This part is not the innovation of the utility model.

[0029] Among them, the longitudinal bending push plate 403, the transverse bending push plate 303 and the clamping block 201 are all made of metal materials. During the use of the longitudinal bending push plate 403, the transverse bending push plate 303 and the clamping block 201, since the longitudinal bending push plate 403, the transverse bending push plate 303 and the clamping block 201 are all in contact with the crane structure, the longitudinal bending push plate 403, the transverse bending push plate 303 and the clamping block 201 are all made of metal materials, so that the longitudinal bending push plate 403, the transverse bending push plate 303 and the clamping block 201 have good hardness and are not easy to be damaged. They are easier to bend when the crane structure is bent and stressed, and are more stable when the crane structure is clamped and fixed without deformation.

[0030] Among them, a slide rail 208 is opened at the top of the bending table 1 near the L-shaped bending mold 101, and a slider 209 slidably connected to the slide rail 208 is installed in the middle of the bottom end of the clamping block 201. When the mobile push frame 202 drives the clamping block 201 to move close to the L-shaped bending mold 101, the slider 209 at the bottom of the clamping block 201 is driven by the driving force and moves synchronously in the slide rail 208, so that the crane structure is clamped when the clamping block 201 is close to the L-shaped bending mold 101, and the crane structure is released when the clamping block 201 is away from the L-shaped bending mold 101.

[0031] Among them, two support plates 206 are fixedly installed on the outer end of the fixed block 2, and a fixing ring 207 that is sleeved with the electric push rod 204 is installed on the top of the two support plates 206. When the electric push rod 204 is in use, its fixing ring 207 is sleeved on the electric push rod 204 and fixedly connected to the support plate 206. The support plate 206 is fixedly installed on the outer end of the fixed block 2. The electric push rod 204 can be installed and fixed by the support plate 206 and the fixing ring 207 to ensure that the electric push rod 204 is stably used.

[0032] Working principle:

[0033] When bending the crane structure, the crane structure is placed on the bending table 1, and the crane structure is placed close to the outer end of the L-shaped bending mold 101. At this time, the electric push rod 204 is started to pass through the through hole 205 and push the movable push frame 202 to move in the direction of the L-shaped bending mold 101, so that the movable push frame 202 drives the clamping block 201 to move to the other side of the crane structure. The crane structure is clamped and fixed by the clamping block 201 and the L-shaped bending mold 101. After the electric push rod 204 pushes the movable push frame 202 and the clamping block 201 to move their positions, the movable push frame 202 and the clamping block 201 are placed against the crane structure to prevent the crane structure from loosening. The horizontal pushing cylinder 301 is driven to drive the telescopic rod a302 to move toward the direction of the crane structure, so that the telescopic rod a302 pushes the horizontal bending push plate 303 to contact the protruding part of the crane structure, and continuously pushes the horizontal bending push plate 303 to bend the crane structure toward the L-shaped bending mold 101. After the crane structure is bent horizontally at a certain angle, the crane structure will become an arc shape and face the longitudinal bending push plate 403, and align with the longitudinal bending push plate 403. At this time, the horizontal pushing cylinder 301 is started to drive the telescopic rod a302 to retract, driving the horizontal bending push plate 303 to move back to its original position, thereby not affecting the working use of the longitudinal bending push plate 403.

[0034] Secondly, the longitudinal push cylinder 401 is started to drive the telescopic rod b402 to move in the direction of the bent crane structure, so that the telescopic rod b402 pushes the longitudinal bending push plate 403 to contact the crane structure after the arc is bent, and the longitudinal bending push plate 403 is continuously pushed to bear force, so that the crane structure after the arc is pushed to completely fit with the L-shaped bending mold 101, so that the crane structure is bent into an L shape, and then the bending work of the crane structure is completed. After the bending process of the crane structure, the electric push rod 204 is started to drive the mobile push frame 202 and the clamping block 201 to move to the left, so that the clamping block 201 is moved away from the outer end of the crane structure, and the limit fixation of the crane structure is released, so as to achieve the purpose of rapid disassembly and assembly, solve the problem that the bolt installation method of the clamp is cumbersome, cannot be quickly disassembled, and the bolts are easily damaged by slipping when loosened and tightened for a long time, thereby improving the bending efficiency of the crane structure.
