Description

Technical Field

[0001] This utility model relates to the field of downhole hydraulic support displacement drive equipment. Background Technology

[0002] Currently, the core of existing integrated cutting-and-expanding construction methods such as "1+2", "2+7", and "X+Y" is to utilize hydraulic supports to reinforce the large-span roof slab of the cutting-and-expanding area along the mountainside, achieving safe and efficient installation through parallel expansion and installation operations. Taking "1+2" ​​as an example, "1" refers to arranging one row of hydraulic supports along the mountainside within the cutting-and-expanding area to reinforce the roof slab, which serves as the first support to be adjusted during cyclical support installation; "2" refers to installing two additional supports after the first support along the mountainside is adjusted to the directional support in each cycle, i.e., one row of supports along the mountainside, together with two basic supports, provides supplementary support, forming a continuous support structure. With the widespread application of the "1+2" ​​integrated cutting-and-expanding construction method, a revolution has been brought about in cutting-and-expanding support theory. This process optimizes the working face expansion and hydraulic support installation processes, transforming the long-standing sequential operations into parallel and simultaneous operations, achieving synchronous and rapid construction of cutting-and-expanding and support installation.

[0003] Among them, the hill-mountain support is a hydraulic support arranged along the direction of the tunnel (hill-mountain direction), mainly used for: 1. Roof reinforcement: Provide temporary support during the process of widening the cut and brushing (expanding the side) to reduce the risk of roof collapse.

[0004] II. Integrated Expansion and Installation: Used in conjunction with the basic support frame, it enables a parallel operation mode of simultaneous painting and installation, improving construction efficiency. III. Composite roof support: Suitable for weak and easily delaminating composite roof conditions, stability is enhanced by a combination of anchor mesh and mountain-mounted supports.

[0005] The traditional deployment process for the mountain-mounted support structure is as follows: Step 1: Use a monorail hoist to transport the hydraulic support, which is used as a mountain support, to the installation platform. At this time, the hydraulic support is still more than 2m away from the installation location. Step 2: Use a single hydraulic cylinder to push the hydraulic support from a distance to the designated installation position. This process requires 2-3 people to work together. It requires the use of a single support column to operate the lateral movement from a distance, which is labor-intensive and carries the risk of the support tipping over.

[0006] In addition, traditional mountain support can be installed by using winches for pulling and hauling, but winches have high safety risks (insufficient reliability of the braking system, wear and breakage of the wire rope, and overload risk), are inconvenient to install and move, and have low levels of intelligence.

[0007] Therefore, how to perform the final 2m lateral movement of the mountain support after the monorail transport is completed has become a technical problem that those skilled in the art need to overcome. Summary of the Invention

[0008] To address the above problems, this utility model proposes a hydraulic support side-pushing device, which can efficiently and stably push the mountain-mounted support laterally, thereby cooperating with a monorail crane to complete the installation of the mountain-mounted support at a designated position.

[0009] The technical solution of this utility model is as follows: it includes a base 2 and an outer sliding slide 3 and an inner sliding slide 5 that are slidably mounted on the base 2; An outer push slide cylinder 4 is also provided between the base 2 and the outer push slide 3. The outer push slide 3 is driven to reciprocate by the outer push slide cylinder 4. The tail of the top surface of the outer push slide 3 also has a push block 31 that can be adjusted by bolts or fixed by welding. An inner push slide cylinder 6 is also provided between the base 2 and the inner push slide 5. The inner push slide 5 is driven to reciprocate by the inner push slide cylinder 6. A roly-poly toy 51 is installed at the front of the inner push slide 5.

[0010] like Figure 3 As shown, the hydraulic support side-pushing device consists of two symmetrically arranged parts, and the bases 2 of these two parts are connected by a detachable pin connection structure; the pin connection structure includes a hinge seat fixedly arranged on the side wall of the base 2 and a pin that connects two adjacent hinge seats in series.

[0011] like Figure 3 As shown, the base 2 is provided with parallel outer guide grooves and inner guide grooves. The outer push slide 3 is slidably installed in the outer guide groove, and the inner push slide 5 is slidably installed in the inner guide groove. Wear-resistant liners are embedded in the guide grooves to reduce the coefficient of friction and extend the service life.

[0012] like Figure 3 As shown, the outer sliding carriage 3 is U-shaped, and the outer sliding carriage cylinder 4 is housed inside the outer sliding carriage 3, with its two ends respectively hinged to the base 2 and the outer sliding carriage 3.

[0013] like Figure 5 As shown, the inner sliding carriage 5 is located at the front of the base 2, and the middle part of the roly-poly 51 is rotatably connected to the groove at the front end of the inner sliding carriage 5, and its center of gravity is located behind the center of rotation, so that the front part of the roly-poly 51 maintains the tendency to extend upward to above the top surface of the inner sliding carriage 5.

[0014] This utility model can be used in conjunction with a monorail crane to move a support frame along a mountain slope to a designated position, ensuring the support frame is flush with the mountain slope. First, the monorail crane transports the support frame onto the outer moving carriage, such as... Figure 6 As shown, the outer sliding carriage cylinder is then used to push the mountain-mounted support against the coal face at the installation position, as shown. Figure 7 As shown, the inner sliding carriage cylinder extends further, pushing the inner sliding carriage outwards. With the help of the self-righting mechanism on the inner sliding carriage, it is then retracted. Afterwards, the outer sliding carriage cylinder retracts. Figure 8 As shown, the outer sliding carriage is then withdrawn to complete the installation of the mountain-mounted support in the designated position. Overall, this project demonstrates high work efficiency, fast installation speed, good stability, and excellent safety protection for operators. Attached Figure Description

Detailed Implementation

[0016] This invention provides a device and method for lateral moving of a downhill support in wellbore, used to solve the installation problem of the downhill support transported by a monorail during the last 2-3 meters of installation. The specific embodiments are described in detail below with reference to the accompanying drawings.

[0017] Traditional hydraulic support installation relies on manual pushing or fixed guide rails, resulting in poor positioning accuracy and insufficient adaptability to underground spaces. Especially when a monorail crane transports the support uphill to a distance of 2-3 meters from the installation point, there is a lack of an efficient lateral pushing mechanism. This invention achieves precise positioning of the support in narrow tunnels through a modular, detachable design, dual-slide collaborative drive, and an automatic anti-reverse mechanism.

[0018] like Figure 1 As shown, the purpose of this operation is to receive the hydraulic support 1 transported by the monorail crane and to move it laterally to complete the final 2-3m of installation.

[0019] like Figure 2 , 3 As shown in Figures 4 and 5, this invention includes a base 2 and an outer sliding slide 3 and an inner sliding slide 5 that are slidably mounted on the base 2. An outer push slide cylinder 4 is also provided between the base 2 and the outer push slide 3. The outer push slide 3 is driven to reciprocate by the outer push slide cylinder 4. A push block 31 is also fixedly installed at the tail of the top surface of the outer push slide 3. In this way, after the outer push slide 3 receives the hydraulic support, the hydraulic support can be driven to move laterally under the resistance of the push block 31 as the outer push slide cylinder 4 moves.

[0020] An inner push slide cylinder 6 is also provided between the base 2 and the inner push slide 5. The inner push slide 5 is driven to reciprocate by the inner push slide cylinder 6. A roly-poly toy 51 is installed at the front of the inner push slide 5.

[0021] like Figure 3 As shown, the hydraulic support side-pushing device consists of two symmetrically arranged parts, and the bases 2 of these two parts are connected by a detachable pin connection structure; the pin connection structure includes a hinge seat fixedly arranged on the side wall of the base 2 and a pin that connects two adjacent hinge seats in series.

[0022] In this way, the symmetrically used hydraulic support side-pushing device can be easily assembled or disassembled, thus better adapting to the equipment size of the mountain support in the length direction. The disassembled hydraulic support side-pushing device also has the advantage of convenient transportation.

[0023] like Figure 3 As shown, the base 2 is provided with an outer guide groove and an inner guide groove that are parallel to each other. The outer push slide 3 is slidably installed in the outer guide groove, and the inner push slide 5 is slidably installed in the inner guide groove.

[0024] like Figure 3 As shown, the outer pusher slide 3 is U-shaped, and the outer pusher slide cylinder 4 is housed inside the outer pusher slide 3, with its two ends hinged to the base 2 and the outer pusher slide 3 respectively. This optimized structural design avoids the drawback of excessively large equipment size, making it impossible to deploy downhole.

[0025] like Figure 5As shown, the inner sliding carriage 5 is located at the front of the base 2. The middle part of the tumbler 51 is rotatably connected to the groove at the front end of the inner sliding carriage 5, and its center of gravity is behind the center of rotation, so that the front part of the tumbler 51 maintains an upward extension to above the top surface of the inner sliding carriage 5. In this way, when the hydraulic support passes the position of the tumbler, the tumbler can tilt down into the groove without affecting the displacement of the hydraulic support; and when the hydraulic support passes the tumbler, the tumbler can naturally tilt up and return to its original position. Afterwards, the tumbler can be used to hold the hydraulic support in place so that the outer sliding carriage can be retracted.

[0026] There are many specific ways to implement this invention. The above description is only a preferred embodiment of this invention. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of this invention, and these improvements should also be considered within the scope of protection of this invention.
