Description

Technical Field

[0001] This utility model relates to the field of building construction technology; specifically, this utility model relates to a leveling layer pouring chute traveling device. Background Technology

[0002] In the construction of new high-speed railways, concrete pouring currently uses chutes connected to steel wire ropes attached to the concrete mixer truck's ladder or rear beam. As concrete is poured, the tension in the steel wire ropes increases, making the concrete mixer truck's ladder or rear beam prone to deformation and breakage, posing a safety hazard. Traditionally, the chutes need to be reinforced before pouring concrete. After reinforcement, the chutes need to be manually moved repeatedly during concrete pouring to achieve the desired effect. However, this method is time-consuming, labor-intensive, and inefficient. Therefore, in order to solve the problems of safety risks, time-consuming, labor-intensive, and inefficient concrete pouring, [further measures are needed]. Utility Model Content

Detailed Implementation

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1

[0029] like Figure 1As shown, this embodiment provides a leveling layer pouring chute walking device, including a support frame 1, a frame 2, walking wheels 3 and limiting wheels 4. The top of the support frame 1 is set in a "U" shape to support the bottom of the chute. The frame 2 is set at the bottom of the support frame 1, and the support frame 1 rotates with the base frame on the horizontal plane, so that the orientation of the chute can be adjusted by rotating the support frame 1, thereby realizing the adjustment of the concrete pouring direction.

[0030] The traveling wheels 3 are located at the four corners of the bottom of the frame 2 to support the base frame to travel on the ground. The traveling wheels 3 are directional wheels to stabilize the traveling direction of the frame 2. In turn, the frame 2 carries the support frame 1 and the chute to move synchronously with the concrete mixer truck to realize the concrete pouring operation.

[0031] The limiting wheel 4 is located at the middle of the bottom of the frame 2, and there are two limiting wheels 4. The two limiting wheels 4 are used to support the two side walls of the groove on the outside of the leveling layer. By cooperating with the side walls of the groove, the limiting wheel 4 can use the groove to stabilize the walking direction of the frame 2, thereby ensuring the stability of the chute and preventing the chute from detaching from the concrete mixer truck.

[0032] Specifically, in this embodiment, the limiting wheel 4 is fixedly installed at the bottom of the frame 2 and located at the front end of the frame 2 in the direction of travel of the frame 2, so as to improve the stability of the frame 2 in the direction of travel and avoid the phenomenon of jamming when the traction force deviates.

[0033] Example 2

[0034] like Figure 2 As shown, the bottom of the frame 2 is provided with a guide rail 5 parallel to the walking direction of the frame 2. The front and rear ends of the guide rail 5 are closed. A suspension frame 6 is slidably provided on the guide rail 5. The limit wheel 4 is installed on both sides of the bottom of the suspension frame 6.

[0035] With the above settings, the position of the limiting wheel 4 can be adjusted at both ends of the frame 2. Then, according to the direction of pouring, the position of the limiting wheel 4 can be moved and adjusted directly in the trench, without having to lift the entire device and put it back on, thus improving the performance.

[0036] Specifically, in this embodiment, hanging rings 7 for connecting traction ropes are fixedly installed on both the front and rear sides of the suspension frame 6. Workers can directly connect the traction rope to the hanging rings 7, and when pouring concrete, the workers can directly pull the traction rope to make the entire device move synchronously with the concrete mixer truck. Moreover, the tension exerted by the traction rope on the entire device is located at its bottom, making the overall movement of the device more stable and less prone to tipping over. At the same time, it improves the stability of the process and ensures the effective implementation of concrete pouring operations.

[0037] Example 3

[0038] like Figures 3 to 5As shown, the leveling layer pouring chute traveling device also includes a tilting frame. The tilting frame includes a first frame 8 whose bottom end is rotatably connected to the frame 2 and a second frame 9 fixedly installed on the end of the first frame 8 away from the frame 2. The second frame 9 is provided with a sliding beam 10 parallel to the traveling direction of the frame 2, and the sliding beam 10 can slide on the second frame 9 in a direction perpendicular to its length. The sliding beam 10 is provided with a sliding sleeve 11, and the top end of the sliding sleeve 11 is rotatably connected to a connecting arm 12. The top end of the connecting arm 12 is rotatably provided with a connecting plate 13 that can be connected to the rear beam of the concrete mixer truck.

[0039] In this embodiment, the tilting frame can be folded inward from its outer end and stored on top of the frame 2, making it easier to transport and use the entire device. After the tilting frame is tilted outward to a horizontal position, the sliding beam 10 can be displaced in the inward and outward directions to adjust the position of the connecting plate 13 in the inward and outward directions. In addition, the sliding sleeve 11 can be adjusted to abut against the second frame 9 in the inward and outward directions by moving forward and backward on the sliding beam 10. Then, by rotating the connecting wall and the connecting plate 13, the connecting plate 13 can be connected to the rear beam of the concrete mixer truck according to the relative position of the concrete mixer truck and the frame 2.

[0040] When connecting the connecting plate 13 to the rear beam of the concrete mixer truck, the sliding sleeve 11 abuts against the front end of the second frame 9 in the direction of movement of the concrete mixer truck, and the connecting wall is tilted forward at its top. When the concrete mixer truck moves, the connecting plate 13, the connecting wall, and the sliding sleeve 11 drive the second frame 9, the first frame 8, and the frame 2 to move synchronously as a whole. This ensures the relative stability of the chute with the concrete mixer truck's chute, improves the concrete pouring effect, and reduces the failure rate. At the same time, it eliminates the need for manual pulling of the traction device to move the entire structure, making it more labor-saving and efficient.

[0041] In this embodiment, both the first frame 8 and the second frame 9 are rectangular structures. The first frame 8 is provided with first auxiliary wheels 14 at both ends of the side closest to the frame 2. The first auxiliary wheels 14 are flush with the walking wheels 3 and have the same height. The bottom of the second frame 9 is provided with two second auxiliary wheels 15 distributed front to back at one end. The second frame 9 is threaded with a lead screw 16 whose bottom end is rotatably engaged with the second auxiliary wheels 15. The lead screw 16 is used to adjust the height of the second auxiliary wheels 15.

[0042] By setting the first auxiliary wheel 14 and the second auxiliary wheel 15, the first frame 8 and the second frame 9 can be stably supported, improving the overall stability of the device. By setting the lead screw 16, the height of the second auxiliary force can be adjusted according to the ground height difference, ensuring that the second auxiliary wheel 15 is always effectively supported on the ground.

[0043] Furthermore, the first frame 8 is rotatably provided with footboards 17 for people to stand on on both the front and rear sides. The footboards 17 can rotate in the front and rear direction with one end connected to the first frame 8, and two first auxiliary wheels 14 are respectively installed on the two footboards 17.

[0044] The pedal 17 can be folded or unfolded by rotating. After the pedal 17 is unfolded, the worker can stand directly on the pedal 17 and rotate the support frame 1 to control the orientation of the chute. At the same time, after the worker stands on the pedal 17, the entire device is driven by the concrete mixer truck to achieve automatic movement, reducing the labor intensity of the worker.

[0045] In the above embodiments, the support frame 1 includes a sleeve rod 1.1, a rotating rod 1.2, and a support rod 1.3. The bottom end of the sleeve rod 1.1 is fixedly installed on the top of the frame 2, the rotating rod 1.2 is rotatably installed inside the sleeve rod 1.1, and the support rod 1.3 is fixed on the top end of the rotating rod 1.2, and the support rod 1.3 is U-shaped. The orientation of the chute can be adjusted by rotating the support rod 1.3.

[0046] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
