[0002] In subway construction, formwork is a temporary or permanent mold used for concrete pouring and shaping. It is mainly used to shape and size the structures such as subway tunnels, stations, and ventilation shafts. Its function is to support the uncured concrete and keep it in the geometric shape required by the design until the concrete hardens and has sufficient strength.

[0003] In reality, when supporting steel pipes, since the diameters of the steel pipes used are not uniform, it is necessary to prepare reinforcement devices of corresponding sizes when fixing the steel pipes. In this process, it is necessary to count the number of fixing devices of different sizes, the placement of the fixing devices, and the transportation of different devices to different locations. These tasks are not only troublesome but also increase the working time. At the same time, when the steel pipes are temporarily replaced, the original reinforcement devices become useless, and new reinforcement devices need to be prepared.

[0004] Meanwhile, a subway construction formwork reinforcement device disclosed in application number CN 215107346 U includes a fixed base A, a second connecting rod A inserted into the right side of the fixed base A, a telescopic rod fixedly connected to the right side of the second connecting rod A, a pressing block fixedly connected to the top of the spring, a second connecting rod B inserted into the right side of the telescopic rod, a second through hole provided on the surface of the second connecting rod B, a damping shock-absorbing spring fixedly connected to the bottom of the fixed base, and a support base fixedly connected to the bottom of the damping shock-absorbing spring.

[0005] However, the following problems were found in the implementation of the relevant technology: the reinforcement device cannot adapt to steel pipes of various sizes, which leads to a lot of time being spent in the early preparation work, thus affecting work efficiency. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a formwork reinforcement device for subway construction, which has the advantage of being suitable for steel pipes of various sizes. This invention solves the problem that reinforcement devices cannot adapt to steel pipes of various diameters, while improving the adaptability of the reinforcement device, reducing its limitations, increasing work efficiency, and making the work more convenient.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a template reinforcement device for subway construction, comprising a reinforcement sleeve, wherein a reinforcement component is provided on the outer side of the reinforcement sleeve, and the reinforcement component includes a motor.

[0008] A main gear is fixedly installed at the end of the motor's main shaft. A gear disk meshes with the outer side of the main gear and rotates inside the reinforcing sleeve. Multiple connecting shafts are movably installed inside the gear disk. A sliding block is fixedly installed on the bottom surface of the connecting shaft, and an arc-shaped plate is fixedly installed on one side of the sliding block.

[0009] Preferably, a plurality of fixing sleeves are fixedly provided on the top surface of the reinforcing sleeve, and a short plate is fixedly provided inside the fixing sleeve, and the short plate is fixedly connected to the motor.

[0010] Preferably, the top surface of the gear disk has multiple arc-shaped grooves, and the connecting shaft moves inside the arc-shaped grooves.

[0011] Preferably, a sliding connecting sleeve is fixedly provided on the bottom surface of the sliding block, and a sliding shaft is slidably connected inside the sliding connecting sleeve.

[0012] Preferably, a reinforcing frame is fixedly provided on the outer side of the reinforcing sleeve, and the reinforcing frame is slidably connected to the sliding block.

[0013] Preferably, the reinforcing sleeve has multiple fixing plates fixedly installed inside, and the fixing plates are fixedly connected to the reinforcing frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention uses a motor to drive a main gear, which in turn drives a gear disc, which in turn drives a connecting shaft. The sliding block moves along with the arc-shaped plate at its front end, while simultaneously fixing the internal steel pipe.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides a formwork reinforcement device for subway construction, including a reinforcement sleeve 1, and a reinforcement component 2 is provided on the outer side of the reinforcement sleeve 1. The reinforcement component 2 includes a motor 201.

[0026] A main gear 202 is fixedly installed at the end of the main shaft of the motor 201. A gear disk 203 meshes with the outer side of the main gear 202 and rotates inside the reinforcing sleeve 1. Multiple connecting shafts 204 are movably installed inside the gear disk 203. A sliding block 205 is fixedly installed on the bottom surface of the connecting shaft 204. An arc plate 206 is fixedly installed on one side of the sliding block 205. The motor 201 drives the main gear 202, which drives the gear disk 203. The gear disk 203 drives the connecting shaft 204, and the sliding block 205 drives the sliding block 205 and the arc plate 206 at its front end to move. At the same time, the internal steel pipe is fixed. This solves the problem that the reinforcing device cannot adapt to steel pipes of various diameters. It also improves the adaptability of the reinforcing device, reduces the limitations of the reinforcing device, improves the efficiency of the work, and makes the work more convenient.

[0027] Specifically, multiple fixing sleeves 5 are fixedly installed on the top surface of the reinforcing sleeve 1. A short plate is fixedly installed inside the fixing sleeve 5, and the short plate is fixedly connected to the motor 201. The fixing sleeve 5 can protect some parts of the reinforcing component 2 from interference during operation, and also fix the motor 201 to maintain its stability during operation.

[0028] Furthermore, the top surface of the gear disk 203 is provided with multiple arc-shaped grooves 2031, and the connecting shaft 204 moves inside the arc-shaped grooves 2031. When the gear disk 203 drives the arc-shaped grooves 2031 to rotate, the inner wall of the arc-shaped grooves 2031 will move with the connecting shaft 204, thereby achieving the purpose of fixing the steel pipe.

[0029] Furthermore, a sliding connecting sleeve 207 is fixedly provided on the bottom surface of the sliding block 205, and a sliding shaft 4 is slidably connected inside the sliding connecting sleeve 207. Through the interaction between the sliding connecting sleeve 207 and the sliding shaft 4, the sliding block 205 is limited to ensure its linear movement.

[0030] It is worth noting that a reinforcing frame 3 is fixedly installed on the outer side of the reinforcing sleeve 1, and the reinforcing frame 3 is slidably connected to the sliding block 205.

[0031] It is worth noting that the internal part of the reinforcing sleeve 1 is fixedly provided with multiple fixing plates 6, and the fixing plates 6 are fixedly connected to the reinforcing frame 3. The fixing plates 6 can fix most of the internal components.

[0032] Among them, motor 201 is prior art and will not be described in detail; at the same time, this utility model also includes a power supply, controller and switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0033] Working principle:

[0034] When using the formwork reinforcement device for subway construction, firstly, the steel pipe joint to be connected is placed inside the reinforcement sleeve 1. Then, the motor 201 in the reinforcement component 2 is turned on. The motor 201 is installed on the outside of the reinforcement sleeve 1 through the fixing sleeve 5. The motor 201 drives the main gear 202, which drives the gear disk 203. When the gear disk 203 rotates, it drives the connecting shaft 204 inside the arc groove 2031. The sliding block 205 drives the sliding block 205 and its front end arc plate 206 to move, while fixing the internal steel pipe. When the connecting shaft 204 slides, it interacts with the sliding shaft 4 inside the reinforcement frame 3 through the sliding connecting sleeve 207, thereby limiting the connecting shaft 204 and keeping it in linear motion. The fixing plate 6 is used to fix the reinforcement frame 3. This utility model solves the problem that the reinforcement device cannot adapt to steel pipes of various diameters, improves the adaptability of the reinforcement device, reduces the limitations of the reinforcement device, improves the efficiency of the work, and makes the work more convenient.
