Description

Technical Field

[0001] The utility model relates to the field of material discharging for trenchless pipeline laying, in particular to a material discharging device for trenchless pipeline laying. Background Art

[0002] Trenchless technology refers to the use of rock drilling, directional measurement and control and other technical means to cross rivers, lakes, important transportation arteries and important buildings without digging trenches on the surface and with minimal damage to the ground structure, to achieve the inspection, laying, repair and replacement of public pipelines such as water supply, gas, natural gas, sewage, telecommunications cables, etc.

[0003] When laying pipelines, discharging equipment is needed. Most of the discharging equipment adopts two sets of relatively rotating roller mechanisms. The pipeline is placed in the channel between the two sets of rollers. The pipeline is transported out little by little through the rotation of the rollers. However, when laying trenchless pipelines, the pipelines used may be different due to different construction projects. Generally, the working size of pipeline discharging equipment is fixed, which requires the preparation and replacement of multiple discharging equipment, which is relatively complicated and affects the laying efficiency and the operating cost of the construction party. Therefore, a discharging device for trenchless pipeline laying is needed. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that the pipeline size carried by the pipeline unloading equipment is generally fixed, and it is not suitable for construction unloading operations of pipelines with different diameters.

[0006] 2. Technical Solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a material discharging device for trenchless pipeline laying, comprising a base, a driven shaft one is rotatably connected to the base, a roller one is connected to the driven shaft one, a driven shaft two is rotatably connected to one side of the driven shaft one on the base, and a roller two cooperating with the roller one is connected to the driven shaft two.

[0008] One end of the base is connected with a bracket one that cooperates with driven shaft one, and a bracket two that cooperates with driven shaft two is connected to the base at one side of bracket one. The base is rotatably connected with a threaded shaft at one end away from bracket one, and a screw sleeve that cooperates with the threaded shaft is connected to the side of bracket two away from roller two. The top of the base is rotatably connected with a support shaft, and a sliding sleeve that cooperates with bracket two and has a slider inside is connected to the support shaft. Threaded ends are connected to the end of the support shaft close to bracket one and the sliding sleeve, and a transmission disk is connected to the top of the driven shaft one and the driven shaft two, and a support column that cooperates with the threaded end is connected to the top of the transmission disk.

[0009] Furthermore, the base is located below the roller and has a transmission shaft that rotates upward on one side. The transmission shaft and the driven shaft are connected and rotated together with a gear transmission mechanism. Through the action of the gear transmission mechanism, the driven shaft drives the roller to rotate synchronously with the transmission shaft.

[0010] Furthermore, a No. 1 motor matched with the transmission shaft is connected upwardly inside the bottom of the base to provide power for the rotation of the transmission shaft, and a No. 2 motor matched with the threaded shaft is connected externally at one end of the base away from the roller to provide power for the rotation of the threaded shaft.

[0011] Furthermore, the support shaft is located above the second roller and is connected with a limiting sliding groove matched with the sliding sleeve, which provides limiting conditions for the sliding sleeve to move on the support shaft and enables it to rotate synchronously with the support shaft.

[0012] Furthermore, the external thread structures of the threaded end above the first roller and the threaded end above the second roller are arranged in opposite directions. This arrangement indirectly regulates the relative rotation directions of the first roller and the second roller, that is, when the two rollers rotate synchronously in opposite directions, it is convenient to discharge the pipe.

[0013] 3. Beneficial Effects

[0014] The advantage of the utility model over the prior art is that the device sets one of the two roller groups to be movable and adjustable, and the position of the rollers can be changed by cooperating with the threaded shaft and the screw sleeve, thereby changing the distance between the two rollers, and adapting to the discharge operation of pipelines with different diameters within a certain range. In order to cooperate with the realization of the above functions, the device is provided with a roller power transmission mechanism consisting of a transmission plate with multiple support columns and a fixed and a movable support shaft, so that the two rollers can still maintain a state of rotating relative to each other for discharge after adjustment.

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] Combined with Figure 1-4 In order to solve the above technical problems, the technical solution provided by the utility model is: a material discharging device for trenchless pipeline laying, comprising a base 1, a driven shaft 5 is rotatably connected on the base 1, a roller 7 is connected on the driven shaft 5, a driven shaft 2 9 is rotatably connected on one side of the driven shaft 5 on the base 1, a roller 2 10 matching with the roller 7 is connected on the driven shaft 2 9, a transmission shaft 2 is rotatably provided on one side of the base 1 below the roller 7, a gear transmission mechanism 4 is rotatably connected between the transmission shaft 2 and the driven shaft 5, and the driven shaft 2 and the driven shaft 5 are rotatably connected together, through the action of the gear transmission mechanism 4, the driven shaft 5 drives the roller 7 to realize synchronous rotation with the transmission shaft 2, and a No. 1 motor 3 matching with the transmission shaft 2 is upwardly connected in the bottom of the base 1 to provide power for the rotation of the transmission shaft 2.

[0025] The pipes for trenchless paving are discharged and conveyed by rollers 1 7 and 10 which are respectively driven by driven shaft 1 5 and driven shaft 2 9. The space between rollers 1 7 and 10 is the area where the pipes are clamped. The base 1 provides support for the device as a whole. Motor 1 3 at the bottom of the base 1 provides power support for the discharge and conveying.

[0026] Embodiment 2

[0027] Combined with Figure 1-6, one end of the base 1 is connected with a bracket 6 that matches with the driven shaft 5, and the base 1 is connected with a bracket 2 8 that matches with the driven shaft 2 9 on one side of the bracket 6. The base 1 is rotatably connected with a threaded shaft 13 at one end away from the bracket 6, and the base 1 is externally connected with a second motor 14 that matches with the threaded shaft 13 at one end away from the roller 7 to provide power for the rotation of the threaded shaft 13. The bracket 2 8 is connected with a screw sleeve 12 that matches with the threaded shaft 13 on the side away from the roller 2 10. The top of the base 1 is rotatably connected with a support shaft 15. The support shaft 15 is connected with a sliding sleeve 18 that matches with the bracket 2 8 and has a slider inside. The support shaft 15 is located above the roller 2 10 and is connected with the sliding sleeve 18 The matching limiting groove 19 provides limiting conditions for the sleeve 18 when it moves on the support shaft 15, and can make it rotate synchronously with the support shaft 15. The support shaft 15 is connected to one end close to the bracket 6 and the sleeve 18 with a threaded end 17. The driven shaft 15 and the driven shaft 2 9 are connected to the top with a transmission disk 16. The top of the transmission disk 16 is connected to a support column 11 matching the threaded end 17. The threaded end 17 above the roller 1 7 and the threaded end 17 above the roller 2 10 are arranged in opposite directions. This arrangement indirectly regulates the relative rotation directions of the roller 1 7 and the roller 2 10, that is, when the two rotate in opposite directions synchronously, it is convenient to discharge the pipeline for transportation.

[0028] The threaded shaft 13 of the second motor 14 is rotated to provide power support. When the bracket 2 8 is installed on the base 1, under the limit conditions generated by the two, the screw sleeve 12 part drives the bracket 2 8 and the parts it supports to move in the base 1, so as to facilitate the adjustment of the material discharge clamping size between the roller 2 10 and the roller 1 7. Through the rotation of the driven shaft 1 5, under the action of the transmission mechanism composed of the transmission disc 16 with multiple support columns 11 and the threaded end 17 above it, the support shaft 15 rotates on the top of the base 1, and under the action of the transmission mechanism composed of the transmission disc 16 and the threaded end 17 above the bracket 2 8, the driven shaft and the roller 2 10 are driven to rotate synchronously but in the same direction. The threaded end 17 that cooperates with the roller 2 10 is arranged on the sliding sleeve 18 of the support shaft 15, so that the threaded end 17 part can also be conveniently moved with the bracket 2 8 in the base 1.

[0029] When the utility model is implemented, the pipe to be laid in a trenchless manner is placed between the two rollers, and the two rollers rotate to discharge and transport the material. This is no different from the use of general pipe discharge equipment. When the diameter of the pipe to be laid changes, the second motor 14 on one side is operated to drive the threaded shaft 13 to rotate, so that the screw sleeve 12 pushes and pulls the bracket 2 8 and the roller 2 10 carried by it to move in the base 1, thereby adjusting the distance between the roller 2 10 and the roller 1 7, so as to facilitate the clamping of pipes of different diameters within a certain range for discharge and transportation. During the adjustment and discharge process, it should be noted that the mechanism of the device is provided with a first motor 3 for power output under the roller 1 7, which is Roller 17 rotates to provide power for feeding. Under the interaction between the support shaft 15 with two threaded ends 17 arranged in opposite directions on the top and the transmission disk 16 on the top of the driven shaft that drives roller 17 to rotate, the support shaft 15 can realize synchronous rotation with the driven shaft 15, and under the interaction between the transmission disk 16 at the top of the driven shaft 29 and another group of threaded ends 17, roller 2 10 can also realize synchronous coordinated rotation with roller 17, thereby completing the material discharge. Roller 2 10 with a movable and adjustable effect has a threaded end 17 on its top that is provided on a sliding sleeve 18, and through the mutual cooperation between the sliding sleeve 18 and the upper limit slide groove 19 of the support shaft 15, the threaded end 17 structure can also move accordingly with the adjustment of roller 2 10 and its position on the support shaft 15.

[0030] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
