Description

Technical Field

[0001] The utility model relates to the technical field of electric pole production equipment, in particular to an electric pole bottom mold clamping device. Background Art

[0002] With the continuous development of cement product technology, cement poles, as an important construction and engineering material, have been widely used in the fields of electricity, communications, etc. The production process of cement poles includes batching, mixing, molding, maintenance and demoulding, and each link directly affects the quality and production efficiency of the poles.

[0003] In the automated production process of cement poles, the use of molds is crucial. Cement pole molds usually consist of two parts: a top mold and a bottom mold. In the demoulding process of cement poles, a crane is needed to lift the top mold and separate the top mold from the bottom mold in order to remove the pole from the mold.

[0004] However, during the demolding process, due to the close adhesion between the top mold and the bottom mold, the overhead crane often lifts the bottom mold together with the top mold. Not only can the electric pole inside the mold not be removed, but the bottom mold will also move out of its original position, causing subsequent production processes to be hindered.

[0005] Therefore, a clamping device is needed to fix the bottom mold of the cement pole when the pole is demoulded, so as to solve the problem that the bottom mold of the pole and the top mold of the pole are difficult to separate. Summary of the invention

[0006] The utility model aims to provide a pole bottom mold clamping device to solve the problems existing in the prior art.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A pole bottom mold clamping device comprises a first power assembly, a fixed frame, a base and a second power assembly, wherein the first power assembly comprises a transmission shaft, the fixed frame is arranged at intervals along the length direction of the transmission shaft, the transmission shaft is rotatably connected to the fixed frame, each of the fixed frames is provided with the base, the base is fixed on the transmission shaft, a first clamping plate and a slide rail are fixed on the base, a second clamping plate is also provided on the base, the second clamping plate is slidably connected to the base via the slide rail, the second power assembly comprises a transmission screw, the transmission screw is arranged parallel to the transmission shaft, and the second clamping plate is rotatably connected to the transmission screw via a screw nut.

[0009] When the utility model is demoulding a cement pole, the first clamping plate and the second clamping plate are used to support the bottom mold of the pole, and then the transmission screw is used to move the second clamping plate toward the first clamping plate to clamp the bottom mold of the pole, so that the bottom mold will not move with the top mold when the overhead crane lifts the top mold. The transmission shaft can make each of the bases rotate synchronously. When the base rotates, it can drive the bottom mold of the pole to flip through the first clamping plate and the second clamping plate, so that the pole rolls out of the bottom mold of the pole, and the demoulding process is completed by itself.

[0010] Preferably, a roller track is provided on one side of the fixed frame, one end of the roller track is connected to the fixed frame, and the other end is provided with a baffle, a buffer assembly and a ramp are provided on the roller track, and the ramp is located between the buffer assembly and the baffle, and the buffer assembly includes a gas spring and a load-bearing plate, one end of the load-bearing plate is hinged to the ramp, and the other end is hinged to the roller track through the gas spring.

[0011] The buffer assembly is used to receive the electric pole rolling out of the electric pole bottom mold. After the electric pole falls onto the load-bearing plate, the gas spring will play a buffering role to prevent the electric pole from falling from a height and directly colliding with the rolling track and causing damage. The electric pole will then roll along the load-bearing plate and the slope, and the electric pole will stop after hitting the baffle, making it easy for the overhead crane to lift it to the storage area.

[0012] Preferably, the first clamp includes a first base plate and a first clamp, the first base plate is detachably connected to the first clamp, the second clamp includes a second base plate and a second clamp, the second base plate is detachably connected to the second clamp, and grooves are respectively provided on the tops of the first clamp and the second clamp, and the grooves are used to place the pole bottom mold.

[0013] The shapes of the first clamp and the second clamp are designed according to the shape of the pole bottom mold. By replacing the first clamp and the second clamp, the first clamp and the second clamp can clamp the pole bottom molds of different shapes.

[0014] Preferably, the first bottom plate is fixed on the base, a sleeve is provided on the first bottom plate, the first bottom plate is rotatably connected to the sleeve, and the transmission screw is arranged through the sleeve.

[0015] When the transmission screw rotates, the first base plate will not move, and the transmission screw will not contact the sleeve during normal operation. If the transmission screw accidentally vibrates during rotation, causing the sleeve to contact the transmission screw, the sleeve will rotate with the transmission screw to avoid damage to the transmission screw and the first base plate.

[0016] Preferably, the second bottom plate is slidably connected to the base via the slide rail, a lead screw nut is provided on the second bottom plate, and the lead screw nut is threadedly connected to the transmission lead screw.

[0017] When the transmission screw rotates, the screw nut will drive the second base plate to move along the slide rail, so that the second clamping plate is close to or away from the first clamping plate, thereby making the first clamping plate and the second clamping plate clamp or loosen the pole bottom mold.

[0018] Preferably, the first power assembly also includes a driving motor and a reducer, the second power assembly also includes a fixed seat, a rotating seat and a screw motor, one end of the transmission shaft is connected to the driving motor through the reducer, and the other end passes through the fixed frame and is rotatably connected to the fixed seat, the rotating seat is fixed on the transmission shaft, the screw motor is arranged on the rotating seat, and the screw motor is connected to the transmission screw.

[0019] The driving motor drives the transmission shaft to rotate through the reducer, thereby driving each of the bases and the rotating seat to rotate synchronously. During this process, the transmission screw and the screw motor can rotate synchronously with the first clamping plate and the second clamping plate, thereby preventing the transmission screw from being broken during rotation.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The utility model utilizes the first clamping plate and the second clamping plate to support the bottom mold of the pole when demoulding the cement pole, and then utilizes the transmission screw to move the second clamping plate toward the first clamping plate to clamp the bottom mold of the pole, so that when the overhead crane lifts the top mold, the bottom mold will not move with the top mold, and the transmission shaft can make each base rotate synchronously, and when the base rotates, it can drive the bottom mold of the pole to flip through the first clamping plate and the second clamping plate, so that the pole rolls out from the bottom mold of the pole, and the demoulding process is completed automatically.

[0030] like Figures 1 to 5 As shown, the specific scheme of the embodiment is as follows: the pole mold includes a pole top mold 1 and a pole bottom mold 2, the cement pole completes the steps of forming and curing in the pole mold, and then the connecting bolts of the pole top mold 1 and the pole bottom mold 2 are removed, and the pole top mold 1 is lifted by a crane to complete demoulding. During this process, the pole mold will be placed on the clamping device of the pole bottom mold 2, and the pole mold will be fixed by the clamping device of the pole bottom mold 2.

[0031] A clamping device for a pole bottom mold 2 includes a first power assembly, a fixed frame 6, a base 7 and a second power assembly. The first power assembly includes a transmission shaft 3, a drive motor 301 and a reducer. The second power assembly includes a transmission screw 4, a fixed seat 5, a rotating seat 501 and a screw motor 401. The rotating seat 501 is arranged on the fixed seat 5, and the screw motor 401 is arranged on the rotating seat 501. The screw motor 401 is connected to the transmission screw 4, and the transmission screw 4 is arranged parallel to the transmission shaft 3.

[0032] Each fixing frame 6 is provided with a base 7, the fixing frame 6 and the fixing seat 5 are respectively fixed on the ground, the fixing frames 6 are arranged at intervals along the length direction of the transmission shaft 3, the transmission shaft 3 passes through each fixing frame 6, the transmission shaft 3 is rotatably connected to the fixing frame 6, one end of the transmission shaft 3 is connected to the driving motor 301 through a reducer, and the other end passes through the fixing frame 6 and is rotatably connected to the fixing seat 5, the base 7 and the rotating seat 501 are respectively fixed on the transmission shaft 3, and the rotating seat 501 and the base 7 are rotatably connected to the fixing seat 5 and the fixing frame 6 through the transmission shaft 3.

[0033] The driving motor 301 drives the transmission shaft 3 to rotate through the reducer, driving each base 7 and the rotating base 501 to rotate synchronously. During this process, the transmission screw 4 and the screw motor 401 will rotate synchronously with the rotating base 501 to prevent the transmission screw 4 from being broken during rotation.

[0034] A first clamp, a slide rail 705 and a second clamp are provided on the top surface of the base 7. The first clamp includes a first bottom plate 701 and a first clamp 702.

The second bottom plate 703 and the second clamp 704 are detachably connected by bolts.

[0035] The first bottom plate 701 and the slide rail 705 are fixed on the top surface of the base 7 , and the second bottom plate 703 is slidably connected to the base 7 via the slide rail 705 , and the slide rail 705 is arranged parallel to the length direction of the driving screw 4 .

If the transmission screw 4 accidentally vibrates during rotation, causing the sleeve to contact the transmission screw 4, the sleeve will rotate with the transmission screw 4 to avoid damage to the transmission screw 4 and the first base plate 701.

[0038] The first clamp 702 and the second clamp 704 are respectively provided with grooves on the top, and the grooves are used to place the pole bottom mold 2. When the first clamp 702 and the second clamp 704 are brought close to each other, they will clamp the protruding part of the pole bottom mold 2, thereby fixing the pole bottom mold 2.

[0039] A raceway 8 is provided on one side of the fixed frame 6, and adjacent raceways 8 are arranged in parallel.

The pole will then roll along the load-bearing plate 802 and the slope. The pole will stop after hitting the baffle, making it easy for the overhead crane to lift it to the storage area.

[0041] The working process of this embodiment is as follows: the pole mold is hoisted to the clamping device of the pole bottom mold 2, the first clamping plate and the second clamping plate on the base 7 are used to support the pole mold, the screw motor 401 is started, the second clamping plate is moved closer to the first clamping plate, and the pole bottom mold 2 is clamped, and then the connecting bolts of the pole top mold 1 and the pole bottom mold 2 are removed, and the top mold is lifted by a crane, and then the drive motor 301 is started, and the transmission shaft 3 drives each of the first clamping plate and the second clamping plate to flip toward the roller 8.
