Abstract
Description
Technical Field
[0001] This utility model belongs to the field of municipal construction technology, specifically relating to a municipal sewage concrete pipe jacking equipment. Background Technology
[0002] A concrete pipe jacking machine is a piece of equipment used for underground pipeline construction, mainly applied to drainage tasks such as urban rainwater, sewage, or farmland irrigation.
[0003] The principle of pipe jacking construction is to use the jacking force generated by the pipe jacking machine to overcome the friction between the pipe and the surrounding soil, push the pipe into the soil at the designed slope, and then transport the excavated soil away.
[0004] Existing pipe jacking machines mostly consist of jacks and a pipe pushing platform, which are usually connected by plug-in clamps. Because workers need to work with the jacks to adjust the position of the pipe pushing platform and the clamps on the jacks, and the clamps need to withstand a large shearing force, they are quite heavy. This makes the operation process labor-intensive and affects work efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a municipal sewage concrete pipe jacking device that can automatically push concrete and reduce manpower consumption.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] A municipal sewage concrete pipe jacking device includes a support guide rail installed at the bottom of a foundation pit, a hydraulic cylinder I sliding on the support guide rail, a support plate for supporting the hydraulic cylinder I, an annular groove formed on the surface of the hydraulic cylinder I, and a pushing platform sliding on the outer wall of the hydraulic cylinder I. A guide frame is provided inside the pushing platform, and a sliding plate is slidably connected to the guide frame. A hydraulic cylinder II is fixedly connected to one side of the guide frame. The driving part of the hydraulic cylinder II pushes the sliding plate to slide on the guide frame. A swing rod is hinged to the upper and lower ends of the sliding plate. The end of the guide frame away from the hydraulic cylinder II is hinged to the middle of a clamping plate. The swing rod is hinged to the clamping plate. A clamping head is provided on the side of the clamping plate away from the hydraulic cylinder II and close to the annular groove. The clamping head corresponds to the annular groove.
[0008] An observation window is provided on the outer wall of the pushing platform at the position corresponding to the clamping head.
[0009] The width of the clamping head is less than the width of the annular groove.
[0010] The clamping head is arc-shaped and matches the curvature of the annular groove.
[0011] The guide frame is slidably connected to a retaining shaft at the end away from the second hydraulic cylinder. The end of the retaining shaft away from the second hydraulic cylinder is a retaining platform. An electromagnetic push rod is provided at the bottom end of the retaining shaft near the second hydraulic cylinder. A spring is sleeved on the outside of the retaining shaft. The spring pushes the retaining shaft to move toward the side away from the second hydraulic cylinder.
[0012] A light-shielding plate is fixedly connected to the outer wall of the card shaft, and a light-transmitting groove is provided on the light-shielding plate;
[0013] The guide frame is equipped with a light sensor, which corresponds to the light-transmitting groove. The light sensor consists of a laser emitter and a laser receiver.
[0014] The light-transmitting groove is cone-shaped, with one end smaller than the other and the other end larger, and it increases linearly.
[0015] The clamping platform is a frustum, and the width and depth of the frustum of the clamping shaft are adapted to each other.
[0016] The technical effects achieved by this utility model are as follows:
[0017] In this invention, the light-transmitting groove is used to block the laser emitted by the laser emitter of the photosensitive unit, and the laser is received by the laser emitter of the photosensitive unit through the laser receiver. By changing the light intensity, it is determined whether the clamping shaft is engaged in the annular groove, so as to facilitate the clamping head to be engaged in the annular groove. This process is automated and does not require manual observation of whether the position of the clamping head and the annular groove corresponds in real time, thus reducing labor consumption.
[0018] This invention utilizes a hydraulic cylinder to drag a sliding plate along a guide frame, causing it to slide away from the hydraulic cylinder. The sliding plate then pushes a swing arm to move away from the hydraulic cylinder, causing the clamping plates to move closer together and engage in the annular groove on the hydraulic cylinder. This achieves power transmission between the hydraulic cylinder and the pushing platform, enabling the pushing and conveying of concrete pipes. The process is automated, eliminating the need for manual adjustment of the clamps and improving work efficiency. Attached Figure Description

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0027] like Figure 1-5 As shown, a municipal sewage concrete pipe jacking device includes a support guide rail 1 installed at the bottom of the foundation pit, a hydraulic cylinder 2 sliding on the support guide rail 1, a support plate 3 for supporting the hydraulic cylinder 2, an annular groove 5 formed on the surface of the hydraulic cylinder 2, and a pushing platform 4 sliding on the outer wall of the hydraulic cylinder 2. A guide frame 7 is provided inside the pushing platform 4, and a sliding plate 8 is slidably connected to the guide frame 7. A hydraulic cylinder 6 is fixedly connected to one side of the guide frame 7. The driving part of the hydraulic cylinder 6 pushes the sliding plate 8 to slide on the guide frame 7. The upper and lower ends of the sliding plate 8 are hinged with swing rods 9. The end of the guide frame 7 away from the hydraulic cylinder 6 is hinged to the middle of the clamping plate 10. The swing rod 9 is hinged to the clamping plate 10. A clamping head 11 is provided on the side of the clamping plate 10 away from the hydraulic cylinder 6 and close to the annular groove 5. The clamping head 11 corresponds to the annular groove 5.
[0028] An observation window is provided on the outer wall of the pushing platform 4 at the position corresponding to the clamping head 11.
[0029] Furthermore, the pusher platform 4 is slidably connected to the support guide rail 1.
[0030] Furthermore, the number of annular grooves 5 is at least two.
[0031] According to the above structure, the slide plate 8 is dragged by the hydraulic cylinder 2 6 and slides on the guide frame 7 toward the side of the hydraulic cylinder 2 6. At this time, the slide plate 8 pulls the swing arm 9 to move toward the side of the hydraulic cylinder 2 6, and makes the clamping plate 10 open away from the end of the hydraulic cylinder 2 6, so as to ensure that the hydraulic cylinder 1 2 can slide on the support guide rail 1, thereby adjusting the push table 4 to correspond with the annular groove 5 at different positions of the hydraulic cylinder 1 2.
[0032] The slide plate 8 is dragged by the hydraulic cylinder 26 and slides on the guide frame 7 toward the side away from the hydraulic cylinder 26. At this time, the slide plate 8 pushes the swing arm 9 to move toward the side away from the hydraulic cylinder 26, and makes the end of the clamping plate 10 away from the hydraulic cylinder 26 approach each other and get into the annular groove 5 on the hydraulic cylinder 12. This realizes the power transmission between the hydraulic cylinder 12 and the pushing table 4, and enables the pushing of the concrete pipe and the conveying of the concrete pipe.
[0033] The process is automated, eliminating the need for manual adjustment of the clips and improving work efficiency.
[0034] See attached document Figure 2 The width of the clamping head 11 is lower than the width of the annular groove 5.
[0035] Based on the above structure, a certain margin is left so that the clamping head 11 can be more easily inserted into the annular groove 5, thereby reducing the difficulty of operation and improving work efficiency.
[0036] See attached document Figures 3 to 5 The clamping head 11 is arc-shaped and matches the arc curvature of the annular groove 5.
[0037] The guide frame 7 is slidably connected to a retaining shaft 16 at the end away from the hydraulic cylinder 2 6. The end of the retaining shaft 16 away from the hydraulic cylinder 2 6 is a retaining platform. An electromagnetic push rod 12 is provided at the bottom end of the retaining shaft 16 near the hydraulic cylinder 2 6. A spring 17 is sleeved on the outside of the retaining shaft 16. The spring 17 pushes the retaining shaft 16 to move toward the side away from the hydraulic cylinder 2 6.
[0038] A light-shielding plate 13 is fixedly connected to the outer wall of the card shaft 16, and a light-transmitting groove 14 is provided on the light-shielding plate 13;
[0039] The guide frame 7 is provided with a light sensor 15, which corresponds to the light-transmitting groove 14. The light sensor 15 is composed of a laser emitter and a laser receiver.
[0040] Furthermore, the light-transmitting groove 14 is used to block the laser emitted by the laser emitter of the light sensor 15, and to receive the laser emitted by the laser emitter of the light sensor 15 through the laser receiver. By changing the light intensity, it is determined whether the clamping shaft 16 is engaged in the annular groove 5, so as to facilitate the clamping head 11 to be engaged in the annular groove 5.
[0041] Furthermore, the electromagnetic push rod 12 pulls out the retaining shaft 16 that is stuck in the annular groove 5.
[0042] Furthermore, the end diameter of the retaining shaft 16 is smaller than the groove width of the annular groove 5.
[0043] According to the above structure, when the clamping shaft 16 corresponds to the annular groove 5, the clamping shaft 16 slides into the annular groove 5 under the action of the spring 17. At this time, the clamping shaft 16 drives the light shield 13 to move, and causes the laser emitter of the light sensor 15 to pass through the light transmission groove 14, and causes the light intensity of the laser receiver of the light sensor 15 to change, thereby transmitting a control signal to the hydraulic cylinder 6 to ensure that the clamping head 11 can be clamped into the annular groove 5.
[0044] The process is automated, eliminating the need for manual observation in real time to ensure that the positions of the clamping head 11 and the annular groove 5 correspond.
[0045] See attached document Figure 5 The light-transmitting groove 14 is generally conical, with one end smaller and the other end larger, and it increases linearly.
[0046] According to the above structure, as the pivot 16 moves, the laser emitted by the laser emitter of the photosensitive unit 15 is blocked by the light-transmitting groove 14, and as the pivot 16 moves at a constant speed, the light intensity received by the laser receiver of the photosensitive unit 15 increases linearly.
[0047] The card platform is a frustum, and the width and depth of the frustum of the card shaft 16 are adapted to each other.
[0048] According to the above structure, when the locking shaft 16 is inserted into the annular groove 5, the hydraulic cylinder 2 moves, and the groove wall of the annular groove 5 on the hydraulic cylinder 2 can push the conical surface of the locking shaft 16 so that the locking shaft 16 moves toward the side closer to the hydraulic cylinder 6.
[0049] When the retaining shaft 16 is not aligned with the annular groove 5, the spring 17 pushes the retaining shaft 16 out of the outer wall of the hydraulic cylinder 2. When the retaining shaft 16 contacts the annular groove 5, the retaining shaft 16 is inserted into the annular groove 5 under the action of the spring 17.
[0050] The working principle of this utility model is as follows: the hydraulic cylinder 12 operates and slides on the support guide rail 1. When the clamping shaft 16 corresponds to the annular groove 5, the clamping shaft 16 slides into the annular groove 5 under the action of the spring 17. At this time, the clamping shaft 16 drives the light shield 13 to move, and causes the laser emitter of the light sensor 15 to pass through the light transmission groove 14, and changes the light intensity of the laser receiver of the light sensor 15. This transmits a control signal to the hydraulic cylinder 26. The operation of the hydraulic cylinder 26 drags the slide plate 8 to slide on the guide frame 7 away from the hydraulic cylinder 26. At this time, the slide plate 8 pushes the swing arm 9 to move away from the hydraulic cylinder 26, and causes the end of the clamping plate 10 away from the hydraulic cylinder 26 to move closer to each other and be clamped into the annular groove 5 on the hydraulic cylinder 12. This realizes the power transmission between the hydraulic cylinder 12 and the pushing table 4, and enables the pushing and conveying of concrete pipes.
[0051] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
