Description

Technical Field

[0001] This application belongs to the technical field of auxiliary transportation equipment for building engineering, specifically relating to a pipe transport trolley that can be used for transporting pipes such as water supply and drainage pipes and fire protection pipes in building construction. Background Technology

[0002] Currently, pipeline transportation at construction sites mostly relies on manual lifting or ordinary flatbed trucks, which has the following drawbacks: manual handling is inefficient and easily damages the pipeline coating; flatbed trucks require additional securing devices to prevent pipelines from rolling; and they have poor maneuverability in complex terrain. Although there are dedicated pipeline transport vehicles, they are complex, bulky, and costly. Therefore, there is an urgent need to design a pipeline transportation tool that is simple in structure, lightweight, prevents rolling off, and is low in cost. Utility Model Content

[0003] The purpose of this application is to provide a pipe-carrying trolley for pipe transportation, which solves the problems of complex operation, low efficiency and easy damage to pipe coating in existing pipe transportation methods.

[0004] The objective of this application is achieved through the following technical solution:

[0005] A pipe transport trolley includes an axle and wheels at both ends of the axle. The axle is connected to the rear end of a push-pull frame, the front end of the push-pull frame is connected to one side of a pipe support, and the other side of the pipe support forms an upward-opening groove in the transverse direction.

[0006] Furthermore, the wheels are solid rubber wheels.

[0007] Furthermore, the push-pull frame is a straight tube, and the push-pull frame is perpendicularly connected to the wheel axle.

[0008] Furthermore, the push-pull bracket is connected to one side of the wheel axle.

[0009] Furthermore, the push-pull bracket and the pipe support are an integral structure or welded together, and there is a curved transition structure between the push-pull bracket and the pipe support.

[0010] Furthermore, the tube support has a curved or bent structure.

[0011] Furthermore, the bracket has an arc-shaped structure.

[0012] Furthermore, the axle and / or the groove are provided with anti-slip pads.

[0013] Furthermore, the axle is provided with a fixed stop on one side and a movable stop on the other side.

[0014] Furthermore, the movable stop includes a ring, a stop head, a nut, and a snap fastener. The ring is sleeved on the axle, and the two ends of the ring opening are connected to the stop head. A snap fastener is sleeved on both stop heads, and a nut is screwed onto the thread formed by the two stop heads. The nut is located above the snap fastener.

[0015] The beneficial effects of this application are:

[0016] (1) Anti-detachment optimization: The push-pull bracket is eccentrically welded and the arc-shaped pipe bracket forms a mechanical self-locking mechanism, so the pipe does not need to be fixed in addition, and the operation is simple and convenient.

[0017] (2) Lightweight: The all-steel structure weighs less than 20kg, which can be operated by a single person, reducing the difficulty of manual operation.

[0018] (3) Strong passability: Solid tires adapt to uneven road surfaces on construction sites and avoid punctures.

[0019] (4) Improved lifespan: Triangular reinforcing ribs reduce the risk of fatigue fracture at weld points.

[0027] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0028] Example 1

[0029] refer to Figures 1-3 As shown, a pipe transport trolley includes an axle 1, wheels 2, a push-pull frame 3, a pipe support 4, a fixed stop 5, and a movable stop 6.

[0030] The axle 1 is arranged horizontally and is used to house the wheels 2 and place the pipes. Rolling wheels 2 are installed at both ends of the axle 1. The trolley moves and turns by the rotation of the wheels 2. The axle 1 is connected to the rear end of the push-pull frame 3, which is used to control the pushing and pulling of the trolley and to facilitate the transition of the frame structure.

[0031] The front end of the push-pull bracket 3 is connected to one side of the pipe bracket 4. The other side of the pipe bracket 4 forms an upward-opening groove in the horizontal direction. The front end of the pipe is locked and placed through the groove formed on the pipe bracket 4, while the rear end of the pipe is placed on the axle 1. After both the front and rear ends of the pipe are supported, the trolley can be pushed and pulled to transport the pipe.

[0032] Wheel 2 is a solid rubber wheel, which is suitable for uneven road surfaces on construction sites and avoids punctures. Solid rubber wheels can be selected with a diameter of 8-14 inches.

[0033] The push-pull frame 3 is a straight pipe. The push-pull frame 3 is vertically welded to the wheel axle 1. The push-pull frame 3 is connected to one side of the wheel axle 1, that is, the pipe body of the push-pull frame 3 is fixed on the eccentric side, so that the pipe is placed in the center, which helps to ensure the stability of the trolley during transportation.

[0034] At the eccentric welding point of the push-pull bracket 3, a triangular steel plate is welded as a reinforcing rib. Its two right-angled sides are fully welded and fixed to the side wall of the steel pipe of the push-pull bracket 3 and the surface of the wheel axle 1, respectively, to distribute the stress at the welding point and prevent cracking after long-term use. The eccentricity of the push-pull bracket 3 is calculated and set to ensure that the pipe can be stably "locked" between the pipe support 4 and the wheel axle 1 within the commonly used pipe diameter range, and is not easy to roll out.

[0035] The push-pull bracket 3 uses a circular or rectangular cross-section steel pipe as the main load-bearing component. The steel pipe is 2-2.5m long, and the length of the steel pipe basically ensures that the center of gravity of the pipeline is at the wheel axle during pipeline transportation. The rear end of the push-pull bracket 3 steel pipe is eccentrically welded to the wheel axle, and the welding point is located 150-200mm off the center line of the wheel axle.

[0036] The pipe bracket 4 has a curved or bent structure, forming a support groove through its own bending or bending. The groove is an arc-shaped structure to match the placement of arc-shaped pipes. The pipe bracket 4 is made of steel strip or rebar bent into an upward-opening semi-arc structure. The steel strip is 3-5cm wide, 3-5mm thick, and has an arc radius R=200mm. The rear end of the steel strip is welded to the front end of the steel pipe of the push-pull bracket 3 to form a cantilever support.

[0037] The push-pull bracket 3 and the pipe support 4 are integral structures or welded together, which facilitates processing and manufacturing and also contributes to the overall structural strength. The push-pull bracket 3 and the pipe support 4 have a curved transition structure to ensure a smooth structure and to facilitate operation and handling.

[0038] Anti-slip pads 7 are provided on the axle 1 and inside the bracket. The anti-slip pads 7 are made of rubber and are used to increase the friction on the pipe and prevent the pipe from sliding back and forth. At the same time, the rubber pads prevent damage to the outer coating of the pipe.

[0039] A fixed stop 5 is provided on one side of the axle 1, and a movable stop 6 is provided on the other side. The stopes on both sides ensure the lateral stability of the pipeline, preventing it from swaying during transport and falling off the trolley. The movable stop 6 allows for adjustment of the clamping distance to accommodate pipelines of different specifications.

[0040] The movable stop 6 includes a ring 601, a stop head 602, a nut 603, and a snap fastener 604. The ring 601 is fitted onto the axle 1, and the two ends of the opening of the ring 601 are welded to the stop head 602. The snap fastener 604 is fitted onto both stop heads 602, and the nut 603 is screwed onto the thread formed by the two stop heads 602, with the nut 603 positioned above the snap fastener 604. By turning the nut 603 downwards, the nut 603 presses against the snap fastener 604, which in turn further tightens the ring 601, thus fixing the movable stop 6. Loosening the nut 603 allows for adjustment of the movable stop 6 through the fitted arrangement of the ring 601.

[0041] A fixed stop 5 is welded to the side of the steel pipe near the push-pull bracket 3 on the axle 1. Short steel bars can be used. A movable stop 6 is set on one side. The lower part of the stop is set on the axle 1 with a ring-shaped kit, and the upper part is set with a screw and ring buckle. The stop can be moved or fixed by adjusting the height of the nut to loosen or tighten the ring-shaped kit. The stop keeps the pipe as centered as possible during transport.

[0042] Example 2

[0043] refer to Figures 1-3 As shown, a pipe transport trolley, based on embodiment 1, uses DN20 steel pipe as the push-pull frame 3 with a length of 2500mm; the wheel axle is equipped with 10-inch pneumatic tires; the eccentricity is set to 150mm; the pipe support 4 has a steel bar diameter of φ14mm and an arc radius R=200mm; the reinforcing rib is a 5mm thick Q235 steel plate.

[0044] The workflow of this embodiment is as follows: During operation, one end of the 6m long DN120 water supply and drainage pipe is placed on the rear axle. The operator holds the middle push-pull frame 3 steel pipe and pushes the trailer into the depth of the pipe until one end of the pipe is placed on the front pipe support and the other end is placed on the rear axle. Then, the push-pull frame steel pipe is operated to push and pull the trolley to realize the pipeline transportation.

[0045] The foregoing basic examples and their further alternative examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in this application. In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.
