Description

Technical Field

[0001] This utility model belongs to the field of building construction machine technology, and in particular relates to a fixing fixture for a building construction machine hydraulic cylinder. Background Technology

[0002] At present, building construction equipment mainly includes pump stations, construction platforms and hydraulic cylinders. In large construction equipment such as 250T building construction machines, the center of gravity of the hydraulic cylinder is prone to shift due to the piston rod slipping out, which causes the hydraulic cylinder to sway significantly during high-altitude hoisting.

[0003] Currently, when hoisting hydraulic cylinders for building construction machines, the oil ports are typically sealed. However, this method only slows down the piston rod's slippage relative to the cylinder barrel; the amount of slippage is still significant, and the hydraulic cylinder still experiences considerable swaying during high-altitude hoisting. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a fixing fixture for the hydraulic cylinder of a building construction machine, which can prevent the hydraulic cylinder from shaking significantly during high-altitude hoisting due to the piston rod slipping out.

[0005] The objective of this utility model is achieved through the following technical solution: A mounting fixture for a hydraulic cylinder in a building construction machine includes: The clamping plate is positioned at the diameter change point of the piston rod end, and the middle of the clamping plate is broken into two detachably connected clamping blocks. Several first lifting earrings, several first lifting earrings are detachably connected to one end of the clamp; Several second lifting lugs, which are detachably connected to one end of the cylinder; Several steel wire ropes, one end of which is detachably connected to several first lifting lugs, and the other end of which is detachably connected to several second lifting lugs.

[0006] The beneficial effects of adopting the above technical solution are as follows: the diameter change point at the end of the piston rod is fixedly connected to the cylinder by a clamping plate, a first lifting lug, a wire rope and a second lifting lug, so as to fix the relative position of the piston rod and the cylinder, thereby avoiding large shaking of the oil cylinder during high-altitude hoisting due to the piston rod slipping out.

[0007] Furthermore, the hydraulic cylinder fixing fixture for the building construction machine includes two horizontal plates. One horizontal plate is detachably connected to one side of the two clamping blocks, and the other horizontal plate is detachably connected to the other side of the two clamping blocks.

[0008] The beneficial effects of adopting the above technical solution are as follows: when clamping the clamping plate at the end of the piston rod where the diameter changes, the two clamping blocks can be fixed by the two horizontal plates to make the clamping plate stably clamped; when removing the clamping plate from the end of the piston rod where the diameter changes, the two horizontal plates can be removed, thereby dividing the clamping plate into two clamping blocks and taking it out.

[0009] Furthermore, two clamping blocks are bolted to both sides of the horizontal plate.

[0010] Furthermore, the first hoisting earring is detachably attached to the horizontal plate.

[0011] Furthermore, one end of the first hoisting ear is threaded onto the horizontal plate.

[0012] Furthermore, one end of the second lifting lug is threaded onto the cylinder.

[0013] Furthermore, a number of first lifting lugs are symmetrically arranged on the clamping plate, and a number of second lifting lugs are symmetrically arranged on the cylinder.

[0014] The beneficial effects of adopting the above technical solution are as follows: this setting helps to make the force between the cylinder and the piston rod symmetrically distributed, so as to avoid excessive force on one side.

[0015] Furthermore, the inner diameter of the clamping plate is larger than the diameter of the piston rod at the variable diameter section but smaller than the diameter of the piston rod at the non-variable diameter section.

[0016] The beneficial effects of adopting the above technical solution are as follows: This setting allows for a gap between the clamping plate and the piston rod at the diameter change point, facilitating angle adjustment by rotation when the clamping plate is installed at the piston rod diameter change point. This allows several first lifting lugs to correspond to several second lifting lugs at their respective positions, thereby facilitating the subsequent installation of the wire rope.

[0017] Furthermore, the two ends of the wire rope are fixedly connected to the first lifting lug and the second lifting lug respectively by shackles and rope clamps.

[0018] The beneficial effects of adopting the above technical solution are as follows: This setting allows the working length of the wire rope to be adjusted by tightening the rope clamp, and the rope clamp to be locked after all the wire ropes are adjusted to the appropriate working length, thereby ensuring that the piston rod and the cylinder can be locked together, thus limiting the piston rod from sliding out. Furthermore, shackles are connected to the first and second lifting earrings.

[0019] The beneficial effects of this utility model are as follows: The piston rod end is fixedly connected to the cylinder by a clamping plate, a first lifting lug, a wire rope, and a second lifting lug, so as to fix the relative position of the piston rod and the cylinder, thereby avoiding large shaking of the hydraulic cylinder during high-altitude hoisting due to the piston rod slipping out. Attached Figure Description

[0020] The present invention will be described in more detail below based on embodiments and with reference to the accompanying drawings. Wherein: Figure 1 A schematic diagram of the structure of this utility model is shown; Figure 2 Showing Figure 1 Sectional view at point AA; Figure 3 An isometric view of this utility model is shown; In the accompanying drawings, the same parts use the same reference numerals. The drawings are not to scale.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] This utility model provides a fixing fixture for the hydraulic cylinder of a building construction machine, such as... Figure 1-3 As shown, it includes: Clamping plate 1, clamping plate 1 is located at the diameter change point at the end of piston rod 9, and the middle part of clamping plate 1 is broken into two mutually detachable clamping blocks 101; Four first lifting earrings 3 are detachably connected to one end of the clamping plate 1 and are respectively located at the four corners of the clamping plate 1; Four second lifting lugs 7 are threadedly connected to one end of the cylinder 8 and are located at the four corners of the cylinder 8 respectively; Four steel wire ropes 4, one end of each of the four steel wire ropes 4 is detachably connected to four first lifting lugs 3, and the other end of each of the four steel wire ropes 4 is detachably connected to four second lifting lugs 7.

[0024] Understandably, the variable diameter section at the end of the piston rod 9 is fixedly connected to the cylinder 8 via the clamping plate 1, the first lifting lug 3, the wire rope 4, and the second lifting lug 7, so as to fix the relative position of the piston rod 9 and the cylinder 8, thereby avoiding large shaking of the hydraulic cylinder during high-altitude hoisting due to the piston rod 9 slipping out.

[0025] It should be noted that one end of the second lifting lug 7 is provided with a threaded part so as to be threadedly connected to the cylinder 8.

[0026] In one embodiment, the hydraulic cylinder fixing fixture for the building construction machine includes two horizontal plates 2. One horizontal plate 2 is bolted to one side of the two clamping blocks 101, and the other horizontal plate 2 is bolted to the other side of the two clamping blocks 101.

[0027] It is understandable that when clamping the clamping plate 1 at the end of the piston rod 9 where the diameter changes, the two clamping blocks 101 can be fixed by the two horizontal plates 2 to make the clamping plate 1 stably clamped; when removing the clamping plate 1 from the end of the piston rod 9 where the diameter changes, the two horizontal plates 2 can be removed, so that the clamping plate 1 can be divided into two clamping blocks 101 and then taken out.

[0028] In one embodiment, the first lifting earring 3 is threaded onto the horizontal plate 2.

[0029] It should be noted that one end of the second lifting ear 7 is also provided with a threaded part so as to be threadedly connected to the threaded hole provided on the horizontal plate 2.

[0030] In one embodiment, four first lifting lugs 3 are symmetrically arranged on the clamping plate 1, and four second lifting lugs 7 are symmetrically arranged on the cylinder 8.

[0031] Understandably, this arrangement is intended to ensure a symmetrical distribution of force between the cylinder 8 and the piston rod 9, thereby preventing excessive force on one side.

[0032] In one embodiment, the inner diameter of the clamping plate 1 is greater than the diameter of the piston rod 9 at the variable diameter section and less than the diameter of the piston rod 9 at the non-variable diameter section.

[0033] Understandably, this arrangement creates a gap between the clamping plate 1 and the piston rod 9 at the diameter change point, allowing for angle adjustment by rotation when the clamping plate 1 is installed at the diameter change point of the piston rod 9. This facilitates the positioning of several first lifting lugs 3 corresponding to several second lifting lugs 7, thereby facilitating the subsequent installation of the wire rope 4.

[0034] In one embodiment, the two ends of the wire rope 4 are fixedly connected to the first lifting lug 3 and the second lifting lug 7 respectively by shackles 6 and rope clamps 5; shackles 6 are connected to the first lifting lug 3 and the second lifting lug 7.

[0035] Understandably, this setup is intended to adjust the working length of the wire rope 4 via the tensioning rope clamp 5, and to lock the rope clamp 5 after all the wire ropes 4 have been adjusted to the appropriate working length, thereby ensuring that the piston rod 9 and the cylinder 8 are interlocked, thus limiting the piston rod 9 from sliding out.

[0036] In summary, by installing the hydraulic cylinder fixing fixture in advance when the hydraulic cylinder is stationary, the entire hydraulic cylinder can be locked, ensuring that the piston rod 9 is in the same position as when stationary. This ensures that there is no shaking caused by center offset during high-altitude hoisting operations, thereby improving the safety factor of high-altitude hoisting operations.
