Description

Technical Field

[0001] The utility model relates to a group mould erecting machine, in particular to a bottom locking device in the group mould erecting machine. Background Art

[0002] The traditional locking device at the bottom of the group mold (machine) uses multiple locking rod assemblies. In each locking rod assembly, one end of the tension rod is fixed to the support at the bottom of the fixed section mold. When in use, the other end is manually pulled up and fixed to the tension support at the bottom of the mobile section mold. In addition, since the rod (tension rod) hangs down when not tightened, it occupies a large space, causing the lifting trolley to collide with it during operation. Summary of the invention

[0003] The utility model aims to provide a bottom locking device in a group vertical mold, which can make a part of the tension rod close to the ground when the tension rod does not need to be tightened, making way for the lifting trolley to travel, thereby effectively solving the problem of collision and interference between the tension rod and the lifting trolley.

[0004] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0005] A bottom locking device in a group mold has a plurality of locking rod assemblies, each of which has a tension rod, a first support fixed to the bottom of a fixed section mold, and a second support fixed to the bottom of a movable section mold; in each of the locking rod assemblies, one end of the tension rod is mounted on the first support, and the other end of the tension rod is mounted on the second support. The technical solution is:

[0006] Each of the locking rod assemblies also has a telescopic cylinder; in each of the locking rod assemblies, the tensioning rod is disconnected in the middle, and the tensioning rod is divided into a short tensioning rod and a long tensioning rod, the length of the long tensioning rod is greater than that of the short tensioning rod, one end of the short tensioning rod is connected to one end of the long tensioning rod, the other end of the short tensioning rod is installed on the first support, and the other end of the long tensioning rod is installed on the second support; one end of the telescopic cylinder (the top end of the piston rod) is connected to a strip-shaped slide groove on the short tensioning rod, and the other end of the telescopic cylinder (the bottom end of the cylinder barrel) is hinged to the first support (at the bottom end).

[0007] In the above technical solution, the preferred technical solution may be that one end of the short tension rod and one end of the long tension rod are preferably connected (hinged) through a pin shaft. The structure in which one end of the telescopic oil cylinder is connected to a strip slide on the short tension rod may be that the short tension rod is fixed with a slot body at one side end installed on the first support, the slot body has an open slot, and the two side walls of the slot body corresponding to the open slot both have strip slides, the number of the strip slides is two, the two strip slides extend laterally along the slot body (extend along the length direction of the slot body), and a limit pin that can slide along the two strip slides crosses the two strip slides, and one end of the telescopic oil cylinder (the top end of the piston rod) is hinged to the limit pin. The ratio of the length of the short tension rod to the length of the long tension rod is preferably 1:2~3. Of course, the length ratio can also be selected in other numerical ranges.

[0008] In the utility model, each locking rod assembly also has a telescopic oil cylinder; in each locking rod assembly, the tension rod is disconnected in the middle, the tension rod is divided into a short tension rod and a long tension rod, one end of the telescopic oil cylinder (the top end of the piston rod) is connected to a strip-shaped slide groove on the short tension rod, and the other end of the telescopic oil cylinder (the bottom end of the cylinder barrel) is hinged to the first support. The utility model adds a telescopic oil cylinder, and the tension rod adopts two rods of different lengths (i.e., a short tension rod and a long tension rod), so that when the tension rod does not need to be tightened, the piston rod of the telescopic oil cylinder is in a retracted state, the short tension rod rotates and drives the long tension rod to fall, and the long tension rod will be close to the ground, that is, the utility model can make a part of the tension rod close to the ground when the tension rod does not need to be tightened, so as to make way for the lifting trolley to travel, thereby effectively solving the problem of collision and interference between the tension rod and the lifting trolley. At the same time, when tightening, with the support of the telescopic oil cylinder, the force of the tension rod on the first support and the second support due to its own weight can be effectively reduced. Furthermore, one end of the telescopic oil cylinder is connected to a strip-shaped slide groove on the short tension rod. This structure allows the telescopic oil cylinder to move a certain distance when tightened. When the telescopic oil cylinder is lifted, it is not necessary to strictly lift the tension rod to a horizontal position, thereby ensuring the safety of the telescopic oil cylinder. According to the test, compared with the related art, after adopting the bottom locking device in the group mold of the utility model, the production efficiency of the group mold machine is increased by more than 8%.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the following embodiments, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0013] Example 1: Figure 1 , Figure 2 , Figure 3 As shown, the bottom locking device in the group mold of the utility model has a plurality of locking rod assemblies 1, each of which has a tension rod 11, a first support 12 fixed to the bottom of the fixed section mold, and a second support 13 fixed to the bottom of the movable section mold. In each of the locking rod assemblies 1, one end of the tension rod 11 is mounted on the first support 12, and the other end of the tension rod 11 is mounted on the second support 13. The reference numeral 15 is a locking nut. Each of the locking rod assemblies 1 also has a telescopic cylinder 14. In each of the locking rod assemblies 1, the tension rod 11 is disconnected in the middle, and the tension rod 11 is divided into a short tension rod and a long tension rod 112. The length of the long tension rod 112 is greater than the length of the short tension rod 111. The ratio of the length of the short tension rod 111 to the length of the long tension rod 112 can be 1:2~3, 1:2 can be selected, and other numerical ranges can also be selected. One end of the short tension rod 111 is connected to one end of the long tension rod 112, the other end of the short tension rod 111 is mounted on the first support 12, and the other end of the long tension rod 112 is mounted on the second support 13. One end (top end of the piston rod) of the telescopic cylinder 14 is connected to a strip-shaped slide groove 114 on the short tension rod 111, and the other end (bottom end of the cylinder) of the telescopic cylinder 14 is hinged to (the bottom end of) the first support 12.

[0014] like Figure 1 , Figure 2 , Figure 3As shown, one end of the short tension rod 111 is connected (hinged) to one end of the long tension rod 112 via a pin 113. The structure in which one end of the telescopic oil cylinder 14 is connected to a strip-shaped slide groove 114 on the short tension rod 111 is that a slot body 115 is fixed to one side end of the short tension rod 111 installed on the first support 12, and the slot body 115 has an open slot. Both side walls of the slot body 115 corresponding to the open slot have strip-shaped slide grooves 114. There are two strip-shaped slide grooves 114. The two strip-shaped slide grooves 114 extend horizontally along the slot body 115, that is, the two strip-shaped slide grooves 114 extend along the length direction of the slot body 115. A limit pin 141 that can slide along the two strip-shaped slide grooves 114) passes through the two strip-shaped slide grooves 114 horizontally, and one end (top end of the piston rod) of the telescopic oil cylinder 14 is hinged to the limit pin 141.

[0015] The bottom locking device in the group mold of the utility model realizes the tensioning and locking of the component through the mobile section mold, the fixed section mold and the locking rod assembly 1. This device effectively prevents the box expansion phenomenon during the pouring of the component. The specific operation process is as follows: ① After the mold reaches the locking position, the telescopic cylinder 14 is started to lift the short tension rod 111 to a nearly horizontal position. ② Manually (operator) lifts the long tension rod 112, installs and fixes it to the second support 13 at the bottom of the mobile section mold, and tightens the locking nut 15 to make the locking rod assembly 1 in a tensioned state to stabilize the mold cavity. ③ Pour concrete to form a component. ④ Open the tension rod to ensure that the device is correct and proceed to the next cycle.

[0016] In the utility model, each locking rod assembly 1 further comprises a telescopic oil cylinder 14; in each locking rod assembly 1, the tension rod 11 is disconnected in the middle, and the tension rod 11 is divided into a short tension rod and a long tension rod 112, one end (top end of the piston rod) of the telescopic oil cylinder 14 is connected to a strip-shaped slide groove 114 on the short tension rod 111, and the other end (bottom end of the cylinder barrel) of the telescopic oil cylinder 14 is hinged to the bottom end of the first support 12. The utility model adds a telescopic oil cylinder 14, and the tension rod 11 adopts two rods of different lengths (i.e., a short tension rod and a long tension rod), so that when the tension rod does not need to be tightened, the piston rod of the telescopic oil cylinder is in a retracted state, the short tension rod rotates and drives the long tension rod to fall, and the long tension rod will be close to the ground, that is, the utility model can make a part of the tension rod close to the ground when the tension rod does not need to be tightened, so as to make way for the lifting trolley to travel, thereby effectively solving the problem of collision and interference between the tension rod and the lifting trolley. At the same time, when tightening, with the support of the telescopic oil cylinder 14, the force of the tension rod 11 on the first support 12 and the second support 13 due to its own weight can be effectively reduced. Furthermore, one end of the telescopic oil cylinder 14 is connected to a strip-shaped slide groove 114 on the short tension rod 111. This structure allows the telescopic oil cylinder 14 to move a certain distance when tightening. When the telescopic oil cylinder 14 is lifted, it is not necessary to strictly lift the tension rod 11 to a horizontal position, thereby ensuring the safety of the telescopic oil cylinder 14. According to the test, compared with the related art, after adopting the bottom locking device in the group mold of the utility model, the production efficiency of the group mold machine is increased by more than 8%.
