Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, and specifically discloses a dredging auxiliary mechanism for municipal pipeline construction. Background Art

[0002] When dredging municipal pipelines, excavation machinery is required to excavate the silt. However, the silt has high viscosity and easily adheres to the crawler of the excavator, resulting in a decrease in the grip of the crawler and even causing the crawler to slip. During construction, it is often necessary to suspend construction to clean the crawler.

[0003] For example, the patent with the authorization announcement number CN212582782U, and the announcement date is February 23, 2021. It discloses a front silt separation device for an excavator, including a main frame, a rack, a first gear, a second gear, a third gear, a fourth gear, a cone wheel and a mudguard; a rack is rotatably connected to the cross arms on both sides of the main frame; a first gear is coaxially sleeved at the tail end of the rack; the first gear is meshed and connected to the second gear; the second gear is meshed and connected to the third gear; the third gear is meshed and connected to the fourth gear; a cone wheel is penetrated and connected to the outside of the middle part of the main frame; this device does not require additional power, and the rack drives the cone wheel to rotate by meshing with the external strip of the excavator crawler.

[0004] When existing silt separation devices including the above patent are in use, since the silt separation device is directly fixedly installed on the excavator, when the excavator is moving forward and encounters a hard protrusion on the ground, it is blocked by the protrusion position, and the hard protrusion on the ground covered by silt cannot be discovered in time, and the silt separation device is easily deformed due to excessive force when blocked by the hard protrusion. Content of the Utility Model

[0005] The purpose of the utility model is to provide a dredging auxiliary mechanism for municipal pipeline construction that can avoid hard protrusions on the ground.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A dredging auxiliary mechanism for municipal pipeline construction includes a baffle and a carrier. An installation rod is fixedly connected to the baffle, the installation rod is rotatably connected to the carrier, and a locking member capable of locking the installation rod to prevent it from rotating is arranged on the carrier.

[0008] For the above-described dredging assistance mechanism, the carrier frame includes a first rod and two groups of second rods. The two groups of second rods are both perpendicular to the first rod, and the two groups of second rods are symmetrically arranged with respect to the first rod. Guide grooves are provided on both second rods along the length direction of the mounting rod. Sliding blocks are slidably mounted in the two guide grooves. The mounting rod is rotatably connected to the corresponding sliding block through a rotating shaft. When the sliding block is at the end of the guide groove close to the baffle, the locking member locks the rotating shaft to prevent it from rotating. An elastic member for maintaining the sliding block at one end of the guide groove is also provided on the second rod.

[0009] For the above-described dredging assistance mechanism, the lower end of the baffle is arc-shaped.

[0010] For the above-described dredging assistance mechanism, the elastic member includes a guide rod arranged in the guide groove. A spring is sleeved on the guide rod. One end of the guide rod is fixedly connected to the corresponding sliding block, and the other end of the guide rod penetrates through the first rod.

[0011] For the above-described dredging assistance mechanism, the locking member includes a plug rod fixedly connected in the guide groove. The plug rod is arranged along the length direction of the guide groove. Insertion holes for cooperating with the plug rod are provided on both the sliding block and the rotating shaft. When the sliding block is at one end of the guide groove, the plug rod is inserted into the insertion holes on the sliding block and the rotating shaft.

[0012] For the above-described dredging assistance mechanism, the height of the mounting rod is lower than that of the first rod, and the end of the mounting rod away from the baffle extends to the lower part of the first rod.

[0013] For the above-described dredging assistance mechanism, wedge blocks are fixedly connected to the mounting rods. After the mounting rod pushes the sliding block to slide along the guide groove and releases the locking of the rotating shaft by the plug rod, the wedge blocks contact the lower part of the first rod.

[0014] For the above-described dredging assistance mechanism, the middle part of the side of the baffle away from the mounting rod protrudes.

[0015] For the above-described dredging assistance mechanism, a limiting block is fixedly connected to the end of the mounting rod away from the baffle. When the plug rod is inserted into the sliding block and the rotating shaft, the limiting block is hooked on the first rod. When the wedge block contacts the first rod, the limiting block is completely separated from the first rod.

[0016] For the above-described dredging assistance mechanism, clamping grooves are provided at both ends of the first rod, and mounting holes are provided at positions corresponding to the clamping grooves on the first rod.

[0017] In the above technical solution, for the dredging assistance mechanism for municipal pipeline construction provided by the present utility model, by rotatably connecting the baffle to the carrier frame and providing a locking member on the carrier frame, when the resistance on the baffle is too large during the forward movement, the locking member releases the locking of the rotating shaft of the baffle, enabling the baffle to rotate and avoid hard protrusions on the ground, thereby preventing the baffle from deforming due to excessive resistance.

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] As Figures 1 - 8 shown, an auxiliary mechanism for dredging in municipal pipeline construction provided by an embodiment of the present utility model includes a baffle 1 and a carrier 2. An installation rod 11 is fixedly connected to the baffle 1, and the installation rod 11 is rotatably connected to the carrier 2. A locking member is provided on the carrier 2 to lock the installation rod 11 so that it cannot rotate.

[0032] The carrier 2 includes a first rod 21 and two groups of second rods 22. The two groups of second rods 22 are both perpendicular to the first rod 21 and are symmetrically arranged with respect to the first rod 21. Guide grooves 221 are formed in the two second rods 22 along the length direction of the installation rod 11. Sliding blocks 222 are slidably installed in the two guide grooves 221. The installation rod 11 is rotatably connected to the corresponding sliding blocks 222 through a rotating shaft 12. When the sliding blocks 222 are at the end of the guide grooves 221 close to the baffle 1, the locking member locks the rotating shaft 12 so that it cannot rotate self - rotatably. An elastic member 4 is also provided on the second rod 22 to maintain the sliding blocks 222 at one end of the guide grooves 221.

[0033] Preferably, the lower end of the baffle 1 is arc - shaped. As Figure 1 shown, the lower part of the baffle 1 bends towards the crawler of the excavator. During the forward movement of the excavator, the arc - shaped lower part of the baffle 1 can effectively reduce the resistance from the silt. Moreover, when the baffle 1 touches a hard bump, the arc - shaped section at its lower end can guide the baffle 1. After the rotating shaft 12 is unlocked, with the thrust applied during the forward movement of the excavator, the baffle 1 has a tendency to rotate.

[0034] The elastic member 4 includes a guide rod 41 arranged in the guide groove 221. A spring 42 is sleeved on the guide rod 41. One end of the guide rod 41 is fixedly connected to the corresponding sliding block 222, and the other end of the guide rod 41 penetrates through the first rod 21.

[0035] The locking member includes a plug rod 3 fixedly connected in the guide groove 221. As Figure 5 shown, the plug rod 3 is arranged along the length direction of the guide groove 221. Jack holes for mating with the plug rod 3 are provided on both the sliding block 222 and the rotating shaft 12. When the sliding block 222 is at one end of the guide groove 221, the plug rod 3 is inserted into the jack holes on the sliding block 222 and the rotating shaft 12.

[0036] Furthermore, the height of the mounting rod 11 is lower than that of the first rod 21, and one end of the mounting rod 11 away from the baffle 1 extends to the lower part of the first rod 21.

[0037] Furthermore, wedge blocks 13 are fixedly connected to the mounting rod 11. After the mounting rod 11 pushes the sliding block 222 to slide along the guide groove 221 and releases the locking of the plug rod 3 on the rotating shaft 12, the wedge blocks 13 contact the lower part of the first rod 21 and can push the mounting rod 11 to rotate.

[0038] Specifically, when the dredging auxiliary mechanism is in use, the two ends of the first rod 21 are respectively installed at the reserved installation positions on the excavator base through fixing members such as bolts, and the first rod 21 is kept horizontally arranged and perpendicular to the two crawlers. As Figure 2 shown, when in the normal use state, one end of the mounting rod 11 away from the baffle 1 is below the first rod 21. During the forward movement of the excavator, when encountering a hard protrusion on the ground, as the excavator moves forward, the arc section at the lower part of the baffle 1 contacts the hard protrusion and is blocked, causing the baffle 1 to push the sliding block 222 to slide along the guide groove 221 towards the position of the first rod 21. When the sliding block 222 slides to the lowest position of the wedge block 13 ( Figure 4 the right end of the wedge block 13 in

[0039] When the baffle 1 passes over the hard protrusion, the push plate no longer exerts a thrust force on the sliding block 222 through the mounting rod 11. At this time, the sliding block 222 slides reversely along the chute under the elastic force of the spring 42. During this process, the baffle 1 rotates reversely under its own gravity. When the sliding block 222 slides reversely and the wedge block 13 is separated from the first rod 21, the mounting rod 11 contacts the first rod 21 again to position the baffle 1, so that the mounting rod 11 no longer rotates after rotating to the horizontal state. At this time, the jack on the rotating shaft 12 is again aligned with the insertion rod 3. The sliding block 222 slides to one end of the guide groove 221 close to the baffle 1 under the elastic force of the spring 42, and the insertion rod 3 is inserted into the jack on the rotating shaft 12 to lock the rotating shaft 12 again and make it unable to rotate.

[0040] The municipal pipeline construction dredging auxiliary mechanism provided by the embodiment of the present utility model rotatably connects the baffle 1 with the carrier 2 and sets a locking member on the carrier 2. When the baffle 1 encounters excessive resistance during forward movement, the locking member releases the locking of the rotating shaft of the baffle 1, so that the baffle 1 can rotate to avoid hard protrusions on the ground, thereby preventing the baffle 1 from deforming due to excessive resistance.

[0041] Furthermore, the middle of the side of the baffle 1 away from the mounting rod 11 protrudes, as Figure 7 shown. During the process of blocking the silt, the protruding position of the baffle 1 can guide the silt to both ends of the baffle 1, that is, Figure 2 the upper side and the lower side of the crawler in the view, reducing the accumulation amount of silt in front of the baffle 1, thereby reducing the resistance when the excavator moves forward.

[0042] In another embodiment proposed by the present utility model, a limiting block 14 is fixedly connected to the end of the mounting rod 11 away from the baffle 1. When the insertion rod 3 is inserted into the sliding block 222 and the rotating shaft 12, the limiting block 14 is hooked on the first rod 21. When the wedge block 13 contacts the first rod 21, the limiting block 14 is completely separated from the first rod 21. With such a setting, during the normal use of the baffle 1, the limiting block 14 can be hooked on the first rod 21 to reduce the acting force exerted by the rotating shaft 12 on the insertion rod 3 when the baffle 1 is blocked by silt during movement, so as to prevent the insertion rod 3 from being damaged. Specifically, the limiting block 14 can also be used as the locking member during implementation.

[0043] In still another embodiment proposed by the present utility model, clamping grooves 211 are formed at both ends of the first rod 21, and mounting holes are formed at positions corresponding to the clamping grooves 211 on the first rod 21.

[0044] Specifically, a clamping block matching the clamping groove 211 is welded on the excavator base. When the clamping block is clamped into the clamping groove 211, the two ends of the first rod 21 can be fixedly connected to the excavator base through bolts.

[0045] Only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, various modifications can be made to the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
