[0002] In recent years, with the further development of underground space resources and the improvement of the demand for convenient highway traffic, a large number of underground comprehensive pipe galleries and highway tunnel projects with complex structures have increased year by year. Tunnel projects and underground pipe galleries include water supply and drainage projects and fire protection projects. Water supply and drainage projects and fire protection projects involve a large number of pipeline installations. The construction method of pipeline installation determines the construction quality, construction progress and work efficiency of pipeline installation. Therefore, pipeline installation in highway tunnels and underground comprehensive pipe galleries is an important part of electromechanical installation construction. In highway tunnels and underground comprehensive pipe galleries, water supply and drainage projects and fire protection projects use a large number of heavy metal pipes, the position of pipe trenches varies, and the amount of pipeline installation projects is large. Especially when working in confined spaces such as highway tunnels and underground comprehensive pipe galleries, the installation of pipelines basically adopts the traditional manual lifting, shoulder resistance and rope pulling operation methods. Manual operation is time-consuming and laborious, and cannot be fully utilized. The work efficiency is low, and safety accidents are prone to occur during operation.

[0015] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. Example

[0016] See also Figure 1-4 ; The assembled pipeline installation auxiliary lifting device described in this embodiment includes a HW100×100 steel mounting frame 1, a 10# channel steel fixing frame 2, an angle steel brace 3 and a channel steel rotating arm 4. The end of the HW100×100 steel mounting frame 1 is provided with a connecting plate, and a circular hole is provided on the plate. The HW100×100 steel mounting frames 1 are connected by bolts. The 10# channel steel fixing frame 2 has circular holes at both ends and in the middle of the web, and the 10# channel steel fixing frame 2 is bolted to the mounting frame 1. One end of the angle steel brace 3 is provided with a positioning column 12, and the other end is provided with a circular hole. The connecting plate at one end of the angle steel brace 3 and one end of the steel side beam 103 are connected by a half-thread bolt. The upper and lower flange plates of the channel steel rotating arm 4 are provided with positioning slots 13, and one end of the channel steel rotating arm 4 is hinged to the steel mounting frame 101 with a hinged plate by a half-thread bolt; the channel steel rotating arm 4 is connected to the lifting mechanism 11.

[0017] When in use, the main structure of the device is formed by connecting the HW100×100 steel mounting frame 1, the channel steel fixing frame 2, the steel mounting frame 101 with a hinged plate, and the chassis steel side beam 103 with bolts, and the height is adjusted by the angle steel diagonal brace 3 and the channel steel rotating arm 4.

[0018] It should be noted that: the connecting plate at one end of the angle steel brace 3 and one end of the steel side beam 103 is connected by a half-thread bolt, so that rotation can be achieved.

[0019] Specifically, the positioning slot 13 of the channel steel rotating arm 4 cooperates with the positioning column 13 at one end of the angle steel diagonal brace 3 to fix the angle of the channel steel rotating arm 4 .

[0020] In this embodiment: the equipment platform plate 5 installed on the upper flange plate of the chassis steel side beam, the universal wheels 7 with brakes installed at both ends of the lower flange plate of the chassis steel side beam, the counterweight plate 6 installed on the equipment platform plate 5, and the counterweight plate is installed away from the side of the channel steel rotating arm.

[0021] When in use, the equipment platform 5 can be used to place a power unit; for metal pipes with larger nominal diameters, there is a risk that the lifting device as a whole may tip forward when the lifting device is working, so installing a counterweight plate 6 on the side away from the channel steel rotating arm 4 can avoid the risk of the lifting device tipping forward.

[0022] It should be noted that reinforcing ribs 14 are provided between the mounting frames 1 to increase the strength of the mounting frames 1 and ensure that the mounting frames 1 do not deform during use.

[0023] See also Figure 1 , Figure 5 ; In combination with the above content: On this basis, a working distance adjustment mechanism 9 is installed below the flange plate on one side of the HW100×100 steel center beam 102.

[0024] In this embodiment: the adjustment mechanism 9 includes a mechanism base 901, a linear guide 902, a lead screw 903, a movable slider 904, and a motor 905. The lead screw 903 is installed in the movable slider 904 through a set thread line. The movable slider 904 is fixed to the linear guide 902 through a reserved hole. The linear guide 902 is inserted into the fixed seats at both ends of the mechanism base 901. The lead screw 903 is inserted into the fixed seats at both ends of the mechanism base 901, and one end is connected to the motor 905. The motor 905 realizes linear reciprocating motion of the movable slider 904.

[0025] Specifically, the HW100×100 steel center beam 102 is fixed to the 10# channel steel fixing frame 2 at one end and to the HW100×100 steel mounting frame 1 at the other end through a connecting plate and bolts.

[0026] Specifically, the electric hoist 10 is fixed to the movable slider 904 , and the motor 905 drives the electric hoist 10 to realize linear reciprocating motion while causing the movable slider 904 to realize linear reciprocating motion.

[0027] See also Figure 1 , Figure 6 , Figure 7 ; Combined with the above content: On this basis, a linear slide rail 8 is installed above the web of the channel steel rotating arm 4, and a slider 801 is installed on the linear slide rail 8; Specifically, in order to ensure that the slider 801 can smoothly perform reciprocating linear motion, the linear guide rail 8 is fixed to the upper part of the web of the channel steel rotating arm 4 by using countersunk hexagonal bolts.

[0028] In this embodiment: one end of the lifting mechanism 11 is fixed to the slide block 801 , and the other end is fixed to the flange plate of the HW100×100 steel mounting frame 1 .

[0029] The lifting mechanism 11 includes a pipe bracket 1101, an articulated shaft seat 1102, and a hydraulic lifting rod 1103. The pipe bracket 1101 has a connecting shaft on one side and is installed above the slider 801. The articulated shaft seat 1102 is fixed to the end of the flange plate of the HW100×100 steel mounting frame 1.

[0030] Specifically, one end of the hydraulic lifting rod (1103) is connected to the connecting shaft on one side of the pipe bracket (1101), and the other end is hinged to the hinge shaft seat (1102). When the channel steel rotating arm 4 rotates a certain angle, the lifting mechanism 11 can rotate a certain angle accordingly.

[0031] First, place the pipeline on the pipeline bracket 1101. The lifting method is divided into two parts. For pipelines with relatively low installation positions, the hydraulic lifting rod 1103 can be started to adjust the height of the channel steel rotating arm 4. The back of the channel steel rotating arm 4 is provided with a positioning slot 13. The positioning column 12 of the angle steel diagonal brace is fixed in the slot 13 of the channel steel rotating arm to realize the conversion of different heights. The channel steel rotating arm 4 is equipped with a slide rail. The jacking mechanism lifts the pipeline to the corresponding height through the linear slide rail, and the construction personnel push the pipeline sideways to install the pipeline. For pipelines with relatively high installation positions, the electric hoist 10 and the position adjustment mechanism 9 can be used to lift the pipeline to the corresponding height for installation by the construction personnel. The device can reduce labor intensity and improve work efficiency; the operation is safe and reliable, and the use is energy-saving and environmentally friendly; the pipeline lifting device adopts an assembled form, which is convenient for disassembly and transportation. It can be widely used in restricted working spaces such as highway tunnels and underground comprehensive pipe galleries, with strong practicality and high reuse rate.
