Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic single column, in particular to a hydraulic single column anti-backward connection device. Background Art

[0002] A single hydraulic prop is composed of a cylinder, piston, and valves. The three-way valve is the heart of the external injection single hydraulic prop. It consists of a check valve, an unloading valve, and a safety valve. The check valve supplies fluid to the single hydraulic prop, the unloading valve unloads the prop back to the prop, and the safety valve ensures the single hydraulic prop maintains constant resistance. This article will use the external injection single hydraulic prop as an example to explain its structure and operating principle.

[0003] The hydraulic single columns erected on site underground are all tied with 2-point steel wire ropes for anti-fall connection. This method of connection is time-consuming and labor-intensive to dismantle when replacing a broken column, and is inefficient. The finished anti-fall chain is relatively bulky and expensive. Summary of the Invention

[0004] The purpose of the utility model is to solve the shortcomings of the connection method in the prior art, such as time-consuming and labor-intensive disassembly when replacing a broken column, low efficiency, and the relatively heavy and expensive finished product anti-fall chain, and to propose a hydraulic single-column anti-fall connection device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A hydraulic single-column anti-fall connection device comprises a curved belt, one end of which is integrally formed with an extension belt, one side of which is provided with a curved cavity, an iron chain is placed inside the curved cavity, and one end of the iron chain is provided with a hanging assembly for hanging the device on a roof anchor net;

[0007] Both sides of the extension belt are provided with connecting plates, and the interior of the connecting plates is provided with mounting components for mounting the extension belt and the iron chain;

[0008] A circular groove is provided on one side of the two connecting plates that are away from each other, and an adjustment component for adjusting the use length of the iron chain is provided inside the circular groove.

[0009] In one possible design, the hanging assembly includes a connecting block fixedly connected to one end of the iron chain, one end of the connecting block is fixedly connected to an arc-shaped hook, the internal rotation of the connecting block is passed through a rotating shaft, both ends of the rotating shaft are fixedly connected to extension plates, one end of the two extension plates is fixedly connected to the same stop block, and the same torsion spring is fixedly connected between one side of the extension plate and one side of the connecting block, and the torsion spring is sleeved on the rotating shaft.

[0010] In a possible design, the mounting assembly includes circular holes opened inside the connecting plate and the extension belt, the internal threads of the plurality of circular holes are penetrated by a same bolt, and the outer wall thread of the bolt is provided with a nut.

[0011] In one possible design, the adjustment assembly includes a sliding rod slidably connected to the inside of a circular groove, one end of the sliding rod is fixedly connected to the inner wall of one side of the circular groove with the same tension spring, one end of the sliding rod is fixedly connected to a side plate, one side of the side plate is fixedly connected to a side rod, one end of the side rod is fixedly connected to a connecting rod, and the two connecting rods are clamped inside the iron chain.

[0012] In a possible design, one end of one of the connecting rods is fixedly connected to a positioning block, and one end of the other connecting rod is provided with a positioning groove, and the positioning block and the positioning groove are engaged with each other.

[0013] In one possible design, a No. 2 socket is provided inside the sliding rod, and a No. 1 socket is provided inside the connecting plate and the extension belt. The same plug rod is clamped inside the No. 1 socket and the No. 2 socket. The top of the plug rod is fixedly connected to a limiting block, and a No. 2 magnet is provided on one side of the limiting block. A No. 1 magnet is provided on one side of one of the connecting plates, and the No. 1 magnet and the No. 2 magnet are attracted to each other.

[0014] In the present application, when in use, two connecting plates are used to clamp the two ends of the extension belt and connect them by gluing. Circular holes are provided inside the connecting plates and the extension belt, and an arc-shaped cavity is provided on one side of the extension belt. At this time, one end of the iron chain can be placed inside the arc-shaped cavity, and a bolt is passed through the circular hole and tightened with a nut to complete the connection between the connecting plate, the extension belt and the iron chain. The arc-shaped belt and the extension belt are made of waste belts, which reduces costs and is simple to manufacture.

[0015] Then hang the arc hook on the top plate anchor net, and select a suitable installation point according to the position of the hydraulic single column and the working environment. Generally speaking, the arc hook should be installed above or on the side of the hydraulic single column so that it can provide effective support when the column falls. At this time, you can first move the block to the inside of the arc hook, leaving a gap for easy installation. The torsion spring can make the block rebound quickly to complete the installation process and prevent the arc hook from falling off.

[0016] And when in use, if the length of the iron chain is too long, you can first pull out the limit block, and the limit block drives the insertion rod to be pulled out to release the braking state of the two sliding rods. At this time, the two side plates can be moved away from each other, and the side plates drive the side rods away, and the side rods drive the connecting rods away. At this time, the positioning block is moved out from the inside of the positioning groove, and the iron chain in the appropriate position can be placed between the two connecting rods. When the device is reset, the two connecting rods are inserted into the inside of the appropriate iron chain, and the actual use length of the iron chain can be adjusted to enhance the applicability of the device.

[0017] Beneficial effects:

[0018] 1. Cost control and resource recycling: By using waste curved belts and extension belts as the main materials, not only the production cost is significantly reduced, but also the recycling of waste materials is achieved, which is in line with the green and environmentally friendly sustainable development concept.

[0019] 2. Flexible structure and easy installation: The design has a pasting connection method for the connecting plate and the extension belt, as well as a quick locking mechanism between the iron chain and the connecting plate through bolts and nuts, which makes the entire device very flexible and convenient during installation and adjustment, thereby improving work efficiency.

[0020] 3. Improved safety performance: The design of the arc hook, torsion spring and block ensures the stability of the device after installation, prevents accidental falling, and provides reliable support for the hydraulic single column. Especially in emergency situations such as pillar tipping, it can quickly provide effective support force to ensure work safety.

[0021] 4. Strong adaptability and easy adjustment: Through the linkage design of the side panels, side rods and connecting rods, combined with the brake release function of the limit blocks and plug rods, users can easily adjust the length of the chain according to actual needs without replacing the entire chain, which greatly enhances the applicability and flexibility of the device.

[0022] 5. Easy operation and low maintenance cost: The entire device has a compact structure and the operation process is simple and easy to understand. Installation, adjustment and maintenance can be completed without complex tools or professional skills, which reduces the usage threshold and subsequent maintenance costs.
