Description

Technical Field

[0001] The utility model relates to the technical field of the removal of relay chamber oil cylinders, in particular to a relay oil cylinder dismounting device. Background Technique

[0002] In recent years, the mid-long distance pipe jacking construction technology in China has been widely applied and developed. Among them, relay chamber indirect jacking is an important technical measure. In the mid-long distance pipe joint jacking, when the thrust of the rear seat oil cylinder does not meet the power required for the front pipe jacking machine to jack, or when continuous jacking will cause damage to the pipe joint, a relay chamber needs to be added at this time for relay jacking construction. After the construction is completed, the oil cylinders in the relay chamber will be disassembled for the next use. Generally, for each relay chamber to be disassembled, the disassembly sequence is generally from the top first, then the two sides, and finally the bottom. Starting from the first relay chamber and disassembling backward, the space for disassembly is continuously jacked forward by the subsequent relay chambers to connect the pipe orifices.

[0003] Generally, the relay chamber oil cylinders are embedded in the inner grooves of the relay chambers and fixed by hoop fasteners. Traditional disassembly methods are generally difficult to carry out, especially the disassembly of the top oil cylinders, which has the greatest potential safety hazards. In the existing oil cylinder disassembly technologies, such as a Chinese patent with the publication number of CN110733987 A for an auxiliary device for removing relay chamber oil cylinders and its construction method, a telescopic arm mechanism is used to meet the requirements of the clamping oil cylinder working positions, which has potential safety hazards. Moreover, for tunnel construction, its structure is complex and large in volume, and it is not applicable to small-diameter pipe jacking construction. Therefore, there is an urgent need to make a reliable disassembly auxiliary tooling to safely and quickly remove the relay chamber oil cylinders. Summary of the Utility Model

Then, at this time, the connection between the oil cylinder and the relay chamber is loosened, and the weights of the oil cylinder and the support are concentrated on the manual hoist, and the manual hoist is synchronously lowered to the ground to achieve the purpose of quickly and safely removing the oil cylinder. Moreover, the support structure fixes the oil cylinder in parallel, effectively preventing lifting eccentric load and avoiding the potential safety hazards of oblique pulling and slanting lifting.

[0006] As a preferred embodiment, the fixed seat includes at least two support frames, which are connected by a longitudinal beam.

The telescopic columns are used to adjust their support height to adapt to oil cylinders in different positions and lifting devices with different lifting heights.

[0008] As a preferred embodiment, the telescopic column includes a fixed column fixed on the hanging beam seat and a movable sleeve column sleeved on the fixed column. The movable sleeve column is slidably matched with the fixed column and the two are locked by screws; to stably support the oil cylinder; the cross beam is connected between the two movable sleeve columns, and a jacking member is provided between the cross beam and the hanging beam seat. The jacking member can be a cylinder or a hydraulic cylinder or a turnbuckle. Through the above adjustment method, the height of the telescopic column can be quickly adjusted.

[0009] As a preferred embodiment, the hoop assembly includes at least two arc-shaped hoop strips, and the two ends of the hoop strips are connected to the corresponding longitudinal beam by bolt members; the design of at least two arc-shaped hoop strips can fix the oil cylinder in multiple ways, prevent risks such as the oil cylinder slipping off, and improve the construction safety.

[0010] As a preferred embodiment, pads are provided at both ends of the hoop strip, and the bolt members are arranged on the pads and fixed to the longitudinal beam by nut members. The cooperation of the bolt members and the nut members ensures the stability of the hoop strip during the fixation of the oil cylinder, and is also convenient for disassembly and assembly.

[0011] As a preferred embodiment, a protective strip is provided on the inner side surface of the hoop strip; during use, the protective strip contacts the oil cylinder, which can not only play an anti-slip role, but also prevent scratches or strangulation on the oil cylinder.

[0012] As a preferred embodiment, the hoop strip is located between the corresponding two arc-shaped support plates to form multiple fixations on the oil cylinder.

[0013] As a preferred embodiment, the hanging beam seat is a rectangular frame seat, and lifting lugs are provided at the four corners of the rectangular frame seat.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Embodiment 1

[0022] As Figure 1As shown in the figure, a relay cylinder disassembly device. As a preferred embodiment, the bracket device in this example includes a lifting beam seat 6, which can be welded by channel steel. A fixing seat 5 is provided on the lifting beam seat 6. The fixing seat is located in the middle of the lifting beam seat. A hoop assembly 2 for fixing the cylinder 1 is provided on the fixing seat 5. The hoop assembly cooperates with the fixing seat to fix the cylinder in parallel, ensuring the stability of the lifting and preventing lifting eccentric load. A lifting lug 7 cooperating with the lifting device 11 is also provided on the lifting beam seat 6. The lifting device hoists the entire bracket device through the lifting lug. During use, the lifting device is connected to the relay room, then the cylinder is fixed to the fixing seat through the hoop assembly. Then, the connection between the cylinder and the relay room is loosened at this time, and the weight of the cylinder and the bracket is concentrated on the lifting device, and the lifting device is synchronously lowered to the ground to achieve the purpose of quickly and safely removing the cylinder. Moreover, this bracket structure fixes the cylinder in parallel, effectively preventing lifting eccentric load and avoiding the safety hazard of oblique pulling and lifting.

[0023] In this embodiment, as a preferred solution, the fixing seat 5 includes at least two support frames 51. In this example, two support frames are taken as an example. In actual construction, 3 or more support frames can be selected according to the relay room and cylinder models, etc., so as to stably support the cylinder. The support frames 51 are connected by a longitudinal beam 52. The longitudinal beam is located on both sides of the support frames, connecting the support frames into one body to ensure the stability of the fixing seat and providing support for the hoop assembly at the same time. In this embodiment, an arc-shaped support plate 53 is provided in the middle of the support frame 51. The hoop assembly 2 is connected to the longitudinal beam 52 and cooperates with the arc-shaped support plate 53 to hold and fix the cylinder 1. The arc-shaped support plate and the hoop assembly fix the cylinder. After fixing, the lifting device is hoisted. Compared with the traditional disassembly method, the disassembly bracket structure of the present invention is light in structure, can be flexibly used for hoisting and disassembling the cylinder, avoids the safety hazard of oblique pulling and lifting, improves the safety requirements for disassembly, and at the same time is simple to manufacture, low in cost and reusable.

[0024] In this embodiment, as a preference, as Figure 2 shown, the lifting beam seat 6 is a rectangular frame seat, and the lifting lugs 7 are arranged at the four corners of the rectangular frame seat; they can also be symmetrically arranged on the corresponding two side edges, as long as it can ensure that the lifting device hoists it smoothly. The lifting device 11 can be a manual hoist or an electric hoist. The manual hoist is connected to the inner ring 9 and the outer ring 8 of the relay room, and hoists the lifting beam seat 6 through the lifting lugs 7 at multiple points. The relay room is located between two concrete pipe sections 10. In this embodiment, there are four lifting lugs, so four manual hoists can be used to hoist the lifting beam seat 6 at four points; the four manual hoists are lifted and lowered simultaneously to disassemble the cylinder smoothly and safely. It should be noted in this embodiment that the minimum lifting height of the bracket is less than the minimum lifting distance of the manual hoist, which can realize the contact and lifting of the cylinder embedded in the relay room.

[0025] The utility model makes the oil cylinder and the bracket fixed as a whole through the cooperation of the hoop assembly and the arc-shaped support plate. When disassembling and hoisting, there is no shaking or inclination. The fixed seat and the hanging beam seat determine the minimum hanging height according to the minimum distance between the two hooks of the manual hoist used, so as to satisfy the contact between the fixed seat and the oil cylinder embedded in the relay room. The 4 lifting lugs distributed on the hanging beam seat make the frame and the oil cylinder more stable during the process of lowering in the high-altitude disassembly and hoisting. The specific implementation is to first hang 4 manual hoists on the 4 corners of the oil cylinder at the top of the relay room, connect the other ends to the disassembly bracket, hoist the bracket to contact the oil cylinder, fix it with a clamp and the oil cylinder, and then tighten the manual hoist. At this time, loosen the connection between the oil cylinder and the relay room, make the oil cylinder and the disassembly bracket an integral body, and be hung by the manual hoist under load. After confirming that the manual hoist is under normal load, completely loosen the connection between the oil cylinder and the relay room, and the 4 manual hoists synchronously descend to the ground, and other auxiliary tools are transported out, thus meeting the safety disassembly requirements of the relay room oil cylinder.

The difference between this embodiment and Embodiment 1 is that in this embodiment, the support frame 51 includes two telescopic columns 51-1. The telescopic columns in this embodiment can adopt telescopic rod members such as cylinders or hydraulic cylinders. The two telescopic columns 51-1 are connected by a cross beam 51-2. The cross beam 51-2 is located below the arc-shaped support plate 53 to support it, improving the bearing capacity of the fixed seat 5. A protective strip is provided on the inner arc surface of the arc-shaped support plate 53; during use, the protective strip contacts the oil cylinder, which can not only play an anti-slip role, but also prevent scratches or strangulation on the oil cylinder. In this embodiment, the telescopic columns are used to adjust their support height to adapt to oil cylinders in different positions and lifting devices with different hanging heights, without being limited by the condition that the minimum hanging height of the bracket is less than the minimum hanging distance of the manual hoist, making the use of the lifting device more flexible and also meeting different construction conditions.
