[0023] The present invention will be further described below with reference to specific embodiments. These specific embodiments are further explanations of the principle of the present invention and are not intended to limit the present invention in any way. Any technology that is the same as or similar to the present invention does not exceed the protection scope of the present invention.

[0024] See Figures 1-6 A steel pipe installation trolley for confined spaces includes an arc-shaped steel support 2, a traveling device, and a hydraulic positioning device. The arc-shaped steel support 2 and the hydraulic positioning device are mounted on the traveling device. The arc-shaped steel support 2 is connected to the hydraulic positioning device. The hydraulic positioning device is used to raise and lower the arc-shaped steel support. Specifically, the traveling device is used to move the arc-shaped steel support 2 and the hydraulic positioning device, and the arc-shaped steel support 2 is used to place or fix the steel pipe to be installed. The arc-shaped structure of the arc-shaped steel support 2 matches the arc-shaped structure of the steel pipe to be installed, ensuring that the steel pipe is stably placed within the arc-shaped steel support 2 without shifting. In use, the steel pipe to be installed is placed or fixed on the arc-shaped steel support 2. Then, the traveling device is operated to move the arc-shaped steel support 2 and the hydraulic positioning device to below the installation position of the steel pipe in the confined space. Next, the hydraulic positioning device is operated to raise or lower the arc-shaped steel support 2 until the steel pipe to be installed reaches the precise installation position for installation.

[0025] Preferably, the steel pipe installation trolley includes a remote control box 7, which is used to control the movement of the walking device and to control the lifting and lowering of the arc-shaped steel support 2 by the hydraulic positioning device. In other words, the remote control box 7 can control the movement of the walking device, and also controls the lifting and lowering of the arc-shaped steel support by the hydraulic positioning device.

[0026] In use, operate the remote control box 7 to control the movement of the walking device so that the steel pipe to be installed reaches below the installation position. Then operate the remote control box 7 to control the hydraulic positioning device to raise or lower the arc-shaped steel support 2, raising or lowering the steel pipe until the steel pipe accurately reaches the installation position to carry out the installation operation.

[0027] In use, as an operational embodiment of the remote control box 7, preferably, the remote control box includes a remote controller; the remote controller is wired to the remote control box 7, and the connecting cable is long enough so that construction personnel can manually operate the remote controller from outside a confined space to control the remote control box 7, thereby controlling the movement of the walking device and the raising and lowering of the hydraulic positioning device. In another embodiment, the remote control box 7 includes a control module and a control parameter input module. During use, construction personnel pre-input the operating parameters of the control module through the control parameter input module, and the control module automatically controls the movement of the walking device and the raising and lowering of the hydraulic positioning device according to the operating parameters. Yet another option is that the remote control box 7 includes a remote controller, which is wirelessly connected to the remote control box; the wireless connection method includes WIFI connection or Bluetooth connection. During use, construction personnel manually operate the remote controller from outside a confined space to control the remote control box 7 via Bluetooth or wireless WIFI, thereby controlling the movement of the walking device and the raising and lowering of the hydraulic positioning device.

[0028] Another preferred embodiment is shown in the appendix. Figure 1 and attached Figure 5 The arc-shaped steel support includes a groove and a rubber strip 1, with the rubber strip 1 positioned in the groove. The rubber strip 1 contacts the steel pipe to be installed, providing cushioning and preventing friction, thus preventing damage to the outer anti-corrosion layer of the steel pipe during construction and transportation.

[0029] Another preferred embodiment is an example of the walking device. Referring to the accompanying drawings, the walking device includes a power unit (not shown), a frame 4, and tires 6; the power unit is connected to the tires 6 and drives the tires 6 to move; the tires 6 are connected to and support the frame 4; the tires 6 are used to support and move the walking device; the frame 4 is used to support the hydraulic positioning device and the arc-shaped steel support 2; the remote control box 7 is mounted on the frame 4; the power unit is connected to the remote control box 7; the remote control box 7 controls the movement of the tires 6 through the power unit, thereby controlling the walking device to move; the connection between the power unit and the remote control box 7 can be selected in various ways, such as a wired connection, or a connection via WIFI or Bluetooth. This utility model is not limited to these methods.

[0030] In use, construction personnel can control the remote control box 7 from outside a confined space via wired or wireless means, or control the remote control box 7 to operate automatically through a control module and preset control parameters, thereby achieving the purpose of controlling the movement of the power unit and the tire 6.

[0031] Another preferred embodiment is an embodiment of the hydraulic positioning device. Referring to the accompanying drawings, the hydraulic positioning device includes a hydraulically controlled jack 3, a motor 8, and hydraulic oil pipes 10; one end of the hydraulically controlled jack 3 is mounted on the frame 4, and the other end is connected to the arc-shaped steel support 2 of the steel pipe mounting trolley; see attached drawings. Figure 6 Preferably, the connection between the hydraulic jack 3 and the arc-shaped steel support 2 can be as follows: the top of the hydraulic jack 3 includes bolt holes, and the bottom of the arc-shaped steel support 2 includes bolt holes; the bolt holes on the top of the hydraulic jack 3 and the bolt holes on the bottom of the arc-shaped steel support 2 are matched with each other and connected by bolts. The hydraulic jack 3 is used to lift or lower the arc-shaped steel support until the steel pipe to be installed reaches the installation position precisely for installation. The motor 8 is connected to the hydraulic oil pipe 10, and the hydraulic jack 3 is connected to the hydraulic oil pipe 10. The motor 8 provides a power source for the hydraulic jack 3 by generating high-pressure hydraulic oil. The hydraulic oil pipe 10 is used to transport the high-pressure hydraulic oil. The hydraulic jack 3 is connected to the remote control box 7. The remote control box 7 is also used to control the lifting and lowering of the hydraulic jack 3. Thus, the remote control box 7 controls the lifting and lowering of the arc-shaped steel support 2 through the hydraulic jack 3, lifting or lowering the arc-shaped steel support 2 until the steel pipe to be installed reaches the installation position precisely for installation. The connection between the hydraulic jack 3 and the remote control box 7 can be selected in various ways, such as a wired connection, or a connection via WIFI or Bluetooth. This utility model is not limited herein. In use, construction personnel control the remote control box 7 from outside a confined space via wired or wireless means, or control the remote control box 7 automatically through a control module and preset control parameters to control the raising and lowering of the arc-shaped steel support 2. After the steel pipe is securely installed, the height of the hydraulic jack 3 is lowered remotely, and the steel pipe installation trolley is removed from the installation work surface.

[0032] See appendix Figure 1In a preferred embodiment, the steel pipe installation trolley includes four sets of hydraulic jacks 3 and bolts 9. Each set of hydraulic jacks 3 has bolt holes at its top, and the bottom of the arc-shaped steel support 2 has corresponding bolt holes. The bolt holes at the top of the hydraulic jacks 3 match the corresponding bolt holes at the bottom of the arc-shaped steel support 2, and are connected to each other using bolts 9. The four sets of hydraulic jacks 3 are respectively connected to the remote control box 7, and each set of hydraulic jacks 3 is independently controlled by the remote control box 7. That is, the four sets of hydraulic jacks 3 receive remote control signals from the remote control box 7 and can operate independently, raising and lowering independently, thereby achieving precise adjustment of the elevation and position of the steel pipe to be installed in different directions. Further, preferably in this embodiment, the steel pipe installation trolley includes multiple hydraulic jacks 3, each connected to the remote control box 7, and each set of hydraulic jacks 3 is independently controlled by the remote control box 7, thereby achieving precise adjustment of the elevation and position of the steel pipe to be installed in different directions.

[0033] Preferably, the steel pipe installation trolley includes a traction ring 5 and bolts 9. The traction ring 5 includes bolt holes, and the front end of the traveling device of the steel pipe installation trolley includes corresponding bolt holes. The bolt holes on the traction ring 5 match the bolt holes at the front end of the traveling device. The traction ring 5 is connected to the traveling device via bolts 9 and the bolt holes. In use, to prevent the trolley from malfunctioning and becoming stuck in a narrow space during operation, a rope is connected to the traction ring 5 before entering the narrow space. If a malfunction occurs, the steel pipe installation trolley can be pulled out of the narrow space via the rope. It should be noted that the bolts connecting the traction ring 5 and the bolts connecting the hydraulic jack 3 can be of the same or different types; this invention does not limit this. For the sake of simplicity in description and drawing, the same terminology is used in this specification, and the bolts in the accompanying drawings are referenced by the same reference numerals, but this does not mean they are of the same type.
