Description

Technical Field

[0001] This utility model relates to the technical field of sliding form lifting devices, specifically a sliding form adaptive lifting device for silo groups. Background Technology

[0002] The slipform lifting device is an important component in the construction of hydraulic slipform. It is the lifting power and load transfer device in the entire slipform construction device. Its working principle is that the motor of the control console drives the high-pressure oil pump, so that the high-pressure oil enters the hydraulic jack through the solenoid reversing valve, oil distributor, needle valve and oil pipeline. Under the action of oil pressure, the hydraulic jack drives the slipform and the operating platform to climb up along the support rod.

[0003] Traditional slipform control using jacks relies on manual labor. The horizontal elevation of each support rod needs to be measured manually and compared using a ruler. This process is prone to human error, which may lead to inconsistent slipform heights of the jacks, affecting construction accuracy. In silo group construction, multiple jacks lift the formwork simultaneously, and the operation of each jack needs precise control. If the slipform heights of each jack are inconsistent, it may cause the formwork to tilt, thereby affecting the geometric accuracy of the silo structure. Therefore, to address the above problems, an adaptive slipform lifting device for silo groups is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an adaptive lifting device for silo group slipform, so as to solve the problem that traditional jack slipform lifting devices rely on manual labor and have poor adaptability.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adaptive sliding formwork lifting device for silo groups includes a hydraulic lifting frame, a sliding formwork frame, a support rod, and hydraulic jacks. The sliding formwork frame is mounted at the bottom of the hydraulic lifting frame. The support rod is slidably connected to the inner side of the hydraulic lifting frame. The hydraulic jacks are mounted on the outer side of the support rod and are installed on the top of the sliding formwork frame. A positioning sleeve is fixedly connected to the inner side of the support rod. A threaded rod is threadedly connected to the inner side of the positioning sleeve. A positioning rod is fixedly connected to the outer side of the threaded rod. A side rod is fixedly connected to the end of the positioning rod away from the threaded rod. The end of the positioning rod away from the threaded rod has uniformly spaced reinforcing grooves. The inner side of the positioning rod has a slot that communicates with the reinforcement groove. The top of the hydraulic lifting frame is fixedly connected to a fixing plate. The top of the fixing plate is detachably connected to a connecting plate by bolts. Two connecting plates form a group. A pull-wire encoder of an external control device is set between a group of connecting plates. The pull-wire encoder includes a body and a measuring wire. The measuring wire is set on the inner side of the body. The connecting plate and the body are fixedly connected. One end of the measuring wire is fixedly connected to a positioning ring. The outer side of the positioning rod is fixedly connected to evenly arranged positioning blocks. The outer side of the positioning ring is fixedly connected to evenly arranged reinforcement rods.

[0007] Preferably, the positioning block is detachably connected to the positioning ring by bolts, and the reinforcing rod is disposed inside the reinforcing groove.

[0008] Preferably, the inner side of the reinforcing rod is provided with a groove, the inner side of the groove is provided with a spring, and a locking block with an arc-shaped end is fixedly connected to the inner side of the groove, the locking block engaging with the inner side of the groove.

[0009] Preferably, one end of the spring is fixedly connected to the inner wall of the groove, and the other end of the spring is fixedly connected to the locking block.

[0010] Preferably, the positioning ring is sleeved on the outside of the side rod, and the positioning ring and the positioning rod are tightly fitted together.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, a structure consisting of a support rod, a positioning rod, a side rod, a reinforcing groove, a wire encoder, and a positioning ring is used. A detachable wire encoder is installed on the top of the hydraulic lifting frame, and detachable positioning rods and side rods are installed on the outside of the support rod. The positioning ring, which is fixedly connected to the measuring line of the wire encoder, is sleeved on the outside of the side rod, thereby obtaining the distance between the side rod and the machine body. The wire encoder transmits the displacement information to the external control device. After receiving the data, the control device determines whether the distance between the side rod and the machine body has decreased to the target distance, thereby controlling the lifting of the hydraulic press lifting frame and driving the sliding mold frame to rise. The entire technical process requires no manual intervention, saving labor. Using a high-precision wire encoder for adaptive judgment makes the lifting of the sliding mold height more accurate, solving the problem of traditional jack template sliding devices relying on manual labor and having poor adaptability.

[0026] An adaptive lifting device for silo group sliding formwork includes a hydraulic lifting frame 1, a sliding formwork frame 2, a support rod 3, and a hydraulic jack 19. The sliding formwork frame 2 is installed at the bottom of the hydraulic lifting frame 1. The support rod 3 is slidably connected to the inner side of the hydraulic lifting frame 1.

A positioning rod 6 is fixedly connected to the outer side of the threaded rod 5. A side rod 7 is fixedly connected to the end of the positioning rod 6 away from the threaded rod 5. A uniformly arranged reinforcing groove 8 is formed at the end of the positioning rod 6 away from the threaded rod 5. A slot 9 communicating with the reinforcing groove 8 is formed on the inner side of the positioning rod 6. A fixed plate 10 is fixedly connected to the top of the lifting frame 1. A connecting plate 11 is detachably connected to the top of the fixed plate 10 by bolts. Two connecting plates 11 form a group. A pull-wire encoder 12 of an external control device is set between a group of connecting plates 11. The pull-wire encoder 12 includes a body 1201 and a measuring line 1202. The measuring line 1202 is set on the inner side of the body 1201. The connecting plate 11 and the body 1201 are fixedly connected. A positioning ring 13 is fixedly connected to one end of the measuring line 1202. Positioning blocks 14 are evenly arranged and fixedly connected to the outer side of the positioning rod 6. Reinforcing rods 15 are evenly arranged and fixedly connected to the outer side of the positioning ring 13. This setting solves the problem that traditional jack template sliding devices rely on manual labor and have poor adaptability.

[0027] The positioning block 14 is detachably connected to the positioning ring 13 by bolts. The reinforcing rod 15 is located inside the reinforcing groove 8, which allows the positioning ring 13 to be disassembled. A sliding groove 16 is provided inside the reinforcing rod 15, and a spring 17 is provided inside the sliding groove 16. A locking block 18 with an arc-shaped end is fixedly connected to the inner side of the sliding groove 16. The locking block 18 is engaged inside the locking groove 9, which allows the reinforcing rod 15 to be reinforced. One end of the spring 17 is fixedly connected to the inner wall of the sliding groove 16, and the other end of the spring 17 is fixedly connected to the locking block 18, which allows the spring 17 to be used in conjunction with the locking block 18. The positioning ring 13 is sleeved on the outside of the side rod 7, and the positioning ring 13 is tightly fitted with the positioning rod 6, which enables the positioning of the positioning ring 13.

[0028] Workflow: All electrical appliances in this invention are equipped with an external power supply or a built-in battery. When the sliding formwork frame 2 is to be lifted by the silo group sliding formwork adaptive lifting device, the wire encoder 12 is placed on top of the hydraulic lifting frame 1, and the connecting plate 11 is attached to the fixing plate 10. The connecting plate 11 and the fixing plate 10 are connected by bolts. Then, the threaded rod 5 is aligned with the positioning sleeve 4 on the inner side of the support rod 3, and the positioning rod 6 and the side rod 7 are rotated to realize the screw thread of the threaded rod 5 and the sleeve, thereby realizing the installation of the threaded rod 5, the positioning rod 6 and the side rod 7. Then, the positioning ring 13, which is fixedly connected to the measuring line 1202, is sleeved on the outside of the side rod 7. The measuring line 1202 will be pulled out of the body 1201 of the wire encoder 12. The reinforcing rod 15 is gradually inserted into the reinforcing groove 8 opened in the positioning rod 6. When the positioning ring 13 is in contact with the positioning rod 6, the locking block 18 will be locked in the inner side of the groove 9. The locking block 18 will first be pressed by the inner wall of the reinforcing groove 8, thereby sliding in the inner side of the slide groove 16 and acting on the spring 17 inside the slide groove 16. When the reinforcing rod 15 moves to the bottom of the reinforcing groove 8, the locking block 18 will be locked in the groove 9, and the spring will... The reaction force generated by spring 17 makes the locking block 18 fit more closely to the inner wall of the slot 9. Then, the positioning block 14 and the positioning ring 13 are connected by bolts, so that the distance between the side rod 7 and the machine body 1201 can be obtained. The external control device will start the hydraulic jack 19. Under the guidance of the support rod 3, the hydraulic jack 19 drives the hydraulic lifting frame 1, the sliding mold frame 2 and the wire encoder 12 to move. The measuring line 1202 of the wire encoder 12 will gradually decrease. The wire encoder 12 will transmit the displacement information to the external control device. After receiving the data, the control device will judge... If the distance between the side rod 7 and the machine body 1201 has decreased to the target distance, the control device connected to the wire encoder 12 will control the hydraulic jack 19 to stop the rise of the hydraulic press lifting frame through a non-intrusive control method. No manual intervention is required in the entire technical process, saving manpower. Using the high-precision wire encoder 12 for adaptive judgment can make the sliding mold height increase more accurate. When a new support rod 3 is to be welded, the threaded rod 5, the positioning rod 6 and the side rod 7 are removed, and the operation is repeated to install the threaded rod 5 in the positioning sleeve 4 inside the new support rod 3.
