Description

Technical Field

[0001] This utility model relates to the technical field of cement pole production equipment, specifically to a quick opening and closing locking device for cement pole molds. Background Technology

[0002] Cement poles are precast columnar concrete components made primarily of cement, sand, and steel reinforcement through processes such as casting and curing. They are characterized by high durability, good load-bearing capacity, and low cost, and are widely used in infrastructure fields such as power, communications, and lighting. The manufacturing process of cement poles mainly includes: first, placing the steel reinforcement cage into a customized mold; then closing the upper and lower molds; pouring a high-strength cement concrete mixture into the mold; followed by a high-speed centrifugal process to compact the concrete and form a hollow structure; then steam curing to accelerate hardening; and finally demolding followed by natural curing to reach the design strength. During the above process, the mold needs to be locked after closing to facilitate subsequent pouring and centrifugation operations. This structure needs to be easy to operate, maintain, and clean, while also possessing sufficient strength to accommodate the manufacture of large cement poles. Traditional one-piece tenon-and-mortise locking structures are prone to deformation and cannot be replaced. Repeated use can affect the mold-closing accuracy, thus reducing the quality of the finished cement pole. A new locking structure is needed to solve these problems. Utility Model Content

[0003] To solve the above problems, this utility model proposes a quick opening and closing locking device for cement pole molds, including a lock box, which is installed on both sides of the lower mold, and lock heads are installed on both sides of the upper mold. The locking pins on the bottom surface of the lock heads can be inserted into the locking channels of the lock box. The limiting pins on the bottom surface of the top plate of the lock box are inserted into the upper end of the return spring, and the lower end of the return spring is inserted into the recessed groove on the top surface of the lifting block. The bottom surface of the lifting block is in contact with the lifting assembly. A pair of sliding pins are provided on each of the two wing plates of the lifting block. The sliding pins are slidably connected to the inclined waist holes of the lock block. The lock block is laterally slidably connected to the lock box and cooperates with the position of the inserted locking pins.

[0004] Furthermore, the lifting assembly includes a cam, which is rotatably connected inside the lock magazine. The cam contacts the bottom surface of the lifting block, and the axle at the head end of the cam extends out of the surface of the lock magazine. A cross groove is opened on the top surface of the axle, and the cross groove engages with the cross key at the end of the swivel handle.

[0005] Furthermore, the locking pin is a rectangular pin with meshing teeth on its side that mate with the side of the locking block. The top surface of the locking block is slidably connected to the bottom surface of the top plate, and the bottom surface of the locking block is slidably connected to the top surface of the limiting block. The limiting block is mounted on the base plate of the lock box by bolts. The two side plates of the lock box are connected to the top plate by bolts to the cover plate. Each plate and the limiting block form a through lock channel inside the lock box.

[0006] Furthermore, the lifting block end face is provided with an indicator post, which is vertically slidably connected to the waist groove opened on the front of the lock box, and the pointer on the end face of the indicator post cooperates with the scale line on one side of the waist groove.

[0007] Furthermore, several ear plates are connected to both sides of the lock box and the lock head. The countersunk holes on the ear plates are connected to the threaded holes at both ends of the upper and lower mold reinforcing hoops by bolts.

[0008] The beneficial effects of this utility model are as follows: This utility model uses a common handle shared by all lifting components to drive the cam to rotate, thereby controlling the lifting block's rise and fall. When the lifting block is lifted by the cam, the locking block retracts, and the locking pin can be freely inserted into the through-hole locking channel. When the lifting block falls, the sliding pin pushes the locking block to slide to both sides through the inclined waist hole, thereby engaging the meshing teeth and locking the locking pin inserted into the lock box, realizing the rapid and tight closing of the upper and lower molds. It has the characteristics of simple structure, convenient operation, and easy cleaning. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 4 As shown, a quick-opening and locking device for a cement pole mold includes a lock box 1, which corresponds to the lock head 4 on the upper and lower sides. Several ear plates 11 are connected to both sides of the lock box 1 and the lock head 4. The countersunk holes on the ear plates 11 are connected to the threaded holes at both ends of the reinforcing hoops of the upper and lower molds by bolts. Usually, the lock head 4 is installed on the upper mold 3, and the lock box 1 is installed on the lower mold 2. The limiting block 10 is connected to the base plate of the lock box 1 by bolts. The side plates 102 and the top plate 101 of the lock box 1 are connected to the cover plate 103 by bolts. Each plate and the limiting block 10 form a through lock channel inside the lock box 1. A rectangular locking post 401 can be inserted into the bottom surface of the lock head 4 in the lock channel. The limiting post on the bottom surface of the top plate 101 of the lock box 1 is inserted into the upper end of the return spring 5, and the lower end of the return spring 5 is inserted into the countersunk groove 601 on the top surface of the lifting block 6.

[0014] In this embodiment, the end face of the lifting block 6 is provided with an indicator post 604, which is vertically slidably connected to the waist groove 104 opened in the cover plate 103. The pointer on the end face of the indicator post 604 is in cooperation with the scale line on one side of the waist groove 104. The bottom surface of the lifting block 6 is in contact with the cam 8 in the lifting assembly. The cam 8 is rotatably connected in the lock box 1. The wheel axle 801 at the head end of the cam 8 passes through the cover plate 103. The top surface of the wheel axle 801 is provided with a cross groove 802, which is in cooperation with the cross key at the end of the handle 9. A pair of sliding posts 603 are provided on each of the two side wing plates 602 of the lifting block 6. The sliding posts 603 are slidably connected to the oblique waist hole 701 of the locking block 7. The top surface of the locking block 7 is slidably connected to the bottom surface of the top plate 101. The bottom surface of the locking block 7 is slidably connected to the top surface of the limiting block 10. The locking block 7 corresponds to the position of the inserted locking post 401. The side of the locking post 401 is provided with a meshing tooth that cooperates with the side of the locking block 7.

[0015] The working principle of this utility model is as follows: When concrete needs to be poured into the mold, the upper and lower molds are closed. At this time, all cams 8 are in the raised position, and the locking pins 401 can be smoothly inserted into the corresponding locking channels. The handle 9 is connected to the cross groove 802, and the cams 8 are rotated by the handle 9, causing the pointer of the indicator pin 604 to move from the upper scale line of the waist groove 104 to the lower scale line. At this time, the return spring 5 can push the lifting block 6 downward. The sliding pin 603 pushes the locking block 7 to slide to both sides through the inclined waist hole 701, thereby engaging the meshing teeth. The locking block 7 locks the locking pin 401 inserted into the locking box 1, realizing the rapid locking of the upper and lower molds. When a device is damaged or deformed, it can be removed and replaced. When cleaning is required, the through locking channels are less likely to accumulate foreign objects that would affect the mold closing accuracy. In addition, the indicator pin 604 can help the operator quickly judge the locking status of the mold.

[0016] This invention enables the upper and lower molds to close quickly and tightly, and features a simple structure, convenient operation, and easy cleaning.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
