Description

TECHNICAL FIELD

[0002] Pipe jacking technology is a trenchless pipe laying construction technology for municipal construction, which has the advantages of little influence on the surrounding environment, small construction site, little noise, and deep underground operation. During the use of pipe jacking, a pipe jacking angle adjusting device is often needed.

[0003] A patent with publication number CN113202976A discloses a deviation correction push plate device installed on the rear shell of a pipe jacking machine head and a deviation correction method thereof. The device includes a deviation correction push plate, a groove for accommodating the deviation correction push plate, which is arranged in the outer wall of the rear shell of the pipe jacking machine head and has an opening, and a power element installed in the groove and connected to the deviation correction push plate. When the power element is started, it controls the deviation correction push plate to make extension and retraction movements relative to the groove. The present application improves the existing pipe jacking machine head equipment and provides a new design of pipe jacking axis deviation correction device. That is, a side deviation correction push plate is added to the rear shell of the pipe jacking machine based on the original pipe jacking deviation oil cylinder system. By opening the side deviation correction push plate, the rear shell is pushed in the opposite direction to cause deflection, thereby accelerating the deviation correction rate of the pipe jacking machine. Under the same deviation correction angle, the present application only needs to push the pipe jacking machine for a shorter distance to achieve the deviation correction operation of the pipe jacking machine.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects of the application easy to understand, the application will be further described below in combination with specific embodiments.

[0022] As Figure 1 ,Figures 3 to 8 As shown, the integrated installation pipe jacking machine device of the embodiment of the present application comprises a support frame 14 and a force arm 15 swingably connected to the outer side surface of the support frame 14, a pipe jacking 12 movably sleeved on the outer side surface of the force arm 15, a fulcrum 151 provided on one end of the force arm 15, a resistance arm 152 symmetrically provided on one side surface of the force arm 15, a fitting auxiliary wheel 154 movably sleeved on the outer side surface of the resistance arm 152 and located at the middle position, a lifting auxiliary wheel 155 movably sleeved on one end of the resistance arm 152, a swing limiting arm plate 144 movably sleeved on the outer side surface of the fulcrum 151 and provided on the bottom surface of the support frame 14, and two groups of hydraulic rods 147 symmetrically fixedly installed on the two side surfaces of the swing limiting arm plate 144.

[0023] The support frame 14 is moved to the two side surfaces of the pipe jacking 12 in cooperation with the hoisting machine, at this time, one end of the force arm 15 is pushed in cooperation with the two groups of hydraulic rods 147, and the fulcrum 151 is used as a support point, so that the force arm 15 rotates around the fulcrum 151, and the fitting auxiliary wheel 154 and the lifting auxiliary wheel 155 on one end surface of the two groups of resistance arms 152 are fitted on the outer side surface of the pipe jacking 12. As the resistance arms 152 continuously swing and press the surfaces of the fitting auxiliary wheel 154 and the lifting auxiliary wheel 155, the surfaces of the fitting auxiliary wheel 154 and the lifting auxiliary wheel 155 gradually slide downward around the arc surface on the bottom surface of the pipe jacking 12, so that the pipe jacking 12 is gradually separated from the ground and floats in the air under the pushing of the fitting auxiliary wheel 154, thereby achieving the effect that the pipe jacking 12 can be quickly fixed by lifting and swinging the resistance arms 152 and pressing the swing limiting arm plate 144, and avoiding the need to adjust and limit the position of the steel wire rope when the pipe jacking 12 is fixed by the steel wire rope, and the need to check whether the pipe jacking 12 is in the center position of the steel wire rope, so that the stability of the pipe jacking 12 cannot be effectively controlled when the pipe jacking 12 is lifted; When the two groups of swing limiting arm plates 144 are respectively clamped at the two end edge positions of the pipe jacking 12, the swing limiting arm plates 144 with a wider size can increase the contact area and contact range between the swing limiting arm plates 144 and the surface of the pipe jacking 12. When the pipe jacking 12 is lifted, the pipe jacking 12 will not shake too much, and more stable support can be provided, the shaking and rotation of the pipe jacking 12 during lifting can be reduced, and the lifting process is more stable. At the same time, the pressing of the swing limiting arm plate 144 and the pipe jacking 12 can uniformly distribute the pressure generated during lifting, reduce the pressure on the local area of the surface of the pipe jacking 12, thereby reducing the risk of damage to the surface of the pipe jacking 12, and better protecting the appearance and structural integrity of the pipe jacking 12.

[0024] As Figure 1 and Figures 3 to 7As shown, the inner side wall surface of the support frame 14 is symmetrically fixedly installed with a wire winder 142, the top surface of the support frame 14 and located at both side edge positions is movably sleeved with a limiting auxiliary rod 141, the output end of the wire winder 142 is fixedly connected with a pulling steel wire 143, the outer side surface of the pulling steel wire 143 is movably overlapped on the outer side surface of the limiting auxiliary rod 141, the top surface of the swing limiting arm plate 144 and located at the middle position is fixedly installed with a limiting support rod 146, one end of the support arm 145 is movably sleeved on the outer side surface of the limiting support rod 146, the outer side surface of the top pipe 12 is provided with a top pipe clamping plate 13, one end of the top pipe 12 is provided with a back top iron 11.

[0025] The lifting machine carries the support frame 14 to move downward into the pit, when the top pipe 12 moves to the surface of the back top iron 11 for lamination, at this time, the staff cooperates to weld the lamination between the top pipe 12 and the back top iron 11, if the top pipe 12 and the back top iron 11 cannot keep the vertical state, the two groups of wire winders 142 in the support frame 14 are used to recover and sink the pulling steel wire 143, so that the limiting support rod 146 on the top surface of the swing limiting arm plate 144 floats up and down around the support arm 145, thereby adjusting the horizontal angle of the top pipe 12, so that one end of the top pipe 12 can be effectively laminated on the outer side surface of the back top iron 11, so that the two groups of support frames 14 are used to stretch and retract the pulling steel wire 143, thereby adjusting the swing angle of the swing limiting arm plate 144, so that the top pipe 12 on the outer side surface of the swing limiting arm plate 144 can be more conveniently and effectively laminated on the outer side surface of the back top iron 11.

[0026] As shown in Figure 1 , Figures 3 to 8 The other end of the pulling steel wire 143 is fixedly connected to the top surface of the swing limiting arm plate 144, the bottom surface of the support frame 14 and located at the middle position is fixedly installed with a support arm 145, the output end of the hydraulic rod 147 is movably overlapped on the outer side surface of the force arm 15, one end surface of the resistance arm 152 and located at one side surface is provided with a support wheel 153, the bottom surface of the swing limiting arm plate 144 is movably overlapped on the outer side surface of the top pipe 12, the outer side surfaces of the lamination auxiliary wheel 154 and the lifting auxiliary wheel 155 are movably overlapped on the outer side surface of the top pipe 12.

[0027] When the swing limiting arm plate 144 carries the top pipe 12 to descend, the supporting wheel 153 is in contact with the ground of the pit first, and the supporting wheel 153 is used as the supporting point. At this time, the hydraulic rod 147 is slowly retracted, and the top pipe 12 is pressed to the sides under its own gravity. The force arm 15 rotates around the fulcrum 151 under the pressing of the top pipe 12, and the force arm 15 swings towards the supporting arm 145. The swinging speed of the force arm 15 and the resistance arm 152 can be controlled according to the retraction speed of the hydraulic rod 147, so that the top pipe 12 slowly moves downward. According to the retraction speed of the hydraulic rod 147, the force arm 15 and the resistance arm 152 slowly swing under the pressing of the top pipe 12, so that the top pipe 12 can slowly separate from the surface of the auxiliary wheel 154.

[0028] As shown in Figures 1 to 2 The outer side surface of the top pipe clamping plate 13 is provided with a clamping limiting groove 131 at the two side edges. The inner side wall of the clamping limiting groove 131 is provided with a non-slip layer. The non-slip layer is movably connected to the outer side surface of the top pipe 12.

[0029] When the two groups of top pipes 12 are welded to the outer side surface of the back top iron 11, the clamping limiting groove 131 at the two ends of the top pipe clamping plate 13 is matched with the outer side surface of the top pipe 12. The position of the two groups of top pipe clamping plates 13 is positioned by the limiting pin rod 132. The position of the top pipe 12 is limited, and the surface of the two groups of top pipes 12 is protected by the top pipe clamping plate 13. Working principle: the supporting frame 14 is moved to the two side surfaces of the top pipe 12 by the crane. At this time, one end of the force arm 15 is pushed by the two groups of hydraulic rods 147, and the fulcrum 151 is used as the supporting point. The two groups of resistance arms 152 rotate around the fulcrum 151, and the auxiliary wheels 154 and the lifting auxiliary wheels 155 on one end surface of the resistance arms 152 are matched with the outer side surface of the top pipe 12. The surface of the auxiliary wheels 154 and the lifting auxiliary wheels 155 is gradually pressed and slid downward around the arc surface on the bottom surface of the top pipe 12, so that the top pipe 12 is gradually separated from the ground and floated in the air. The resistance arms 152 are used to lift and pry, and the pressing of the swing limiting arm plate 144 is limited, so that the top pipe 12 can be quickly fixed. When the two sets of swing limiting arm plates 144 are clamped at the edge positions of the top pipe 12 respectively, the swing limiting arm plates 144 with a wider size can increase the contact area and contact range between the swing limiting arm plates 144 and the surface of the top pipe 12. When the top pipe 12 is lifted, the top pipe 12 will not shake too much, which can provide more stable support and reduce the shaking and rotation of the pipe during lifting, so that the lifting process is more stable. At the same time, the extrusion of the swing limiting arm plates 144 and the top pipe 12 can evenly distribute the pressure generated during lifting, reduce the pressure on the local area of the surface of the top pipe 12, thereby reducing the risk of damage to the surface of the pipe, and better protecting the appearance and structural integrity of the top pipe 12. When the lifting machine carrying the support frame 14 moves downward into the pit, the top pipe 12 moves to the surface of the back top iron 11 for lamination. At this time, the staff welds the lamination between the top pipe 12 and the back top iron 11. If the top pipe 12 and the back top iron 11 cannot maintain a vertical state, the two sets of disc wire devices 142 in the support frame 14 are used to recover and sink the pulling steel wire 143, so that the limiting support rod 146 on the top surface of the swing limiting arm plate 144 floats up and down around the support arm 145, thereby adjusting the horizontal angle of the top pipe 12, so that one end of the top pipe 12 can effectively laminate on the outside surface of the back top iron 11. The effect of adjusting the swing angle of the swing limiting arm plate 144 by stretching and contracting the pulling steel wire 143 by the two sets of support frames 14 is achieved, so that the top pipe 12 on the outside surface of the swing limiting arm plate 144 can be more conveniently and effectively laminated on the outside surface of the back top iron 11. When the swing limiting arm plate 144 carrying the top pipe 12 descends, the support wheel 153 contacts the ground of the pit first and takes the position of the support wheel 153 as the support point. At this time, the hydraulic rod 147 slowly retracts the telescopic rod. At this time, the top pipe 12 will extrude and push the lamination auxiliary wheel 154 to both sides under its own gravity. The force arm 15 without support will rotate around the fulcrum 151 under the extrusion and pushing of the top pipe 12, and make the force arm 15 swing towards the support arm 145. The swing speed of the force arm 15 and the resistance arm 152 can be controlled according to the retraction speed of the hydraulic rod 147, so that the top pipe 12 slowly moves downward. The effect of slowly swinging the force arm 15 and the resistance arm 152 under the pressure of the top pipe 12 according to the retraction speed of the hydraulic rod 147 is achieved, so that the top pipe 12 can slowly separate from the surface of the lamination auxiliary wheel 154.
