Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to a power assist system which facilitates construction workers to enter pipelines with smaller diameters for construction. Background Art

[0002] Our company was working on a DN800 water supply improvement project on Dongfang Road (Eshan Road-Weifang Road), requiring stainless steel lining repairs within an 800mm diameter pipeline. Due to the inability to properly access a work pit, the length of the single stainless steel lining repair section was increased to over 200 meters. The small diameter of the pipeline and the long construction distance required workers to reach the designated work site, which was time-consuming and labor-intensive. Utility Model Content

[0003] The utility model aims to solve the above technical problems and provide a power assist system that facilitates construction workers to enter smaller diameter pipelines for construction, which saves time and effort while effectively reducing construction costs.

[0004] In order to solve the above technical problems, the embodiment of the present utility model provides a power assist system that facilitates construction workers to enter small-diameter pipelines for construction. The power assist system operates in small-diameter pipelines and includes:

[0005] A first tractor provided at one end of the small-diameter pipeline;

[0006] A second tractor installed at the other end of the small-diameter pipeline;

[0007] A cart system suitable for small-diameter pipes, with adjacent carts connected by a detachable connection mechanism;

[0008] The head trolley of the trolley system is connected to the second traction machine through a wire rope, the tail trolley of the trolley system is connected to the first traction machine through a wire rope, and the port of the small-diameter pipeline is provided with a wire rope steering device. The number of trolleys in the trolley system is N≥2.

[0009] Furthermore, the detachable connection mechanism includes: circular joints provided at both ends of the cart;

[0010] The ring joints between adjacent carts are connected by pins.

[0011] Furthermore, at least one of the carts in the cart system is equipped with a stainless steel repair material fixing base, and the stainless steel repair material fixing base includes:

[0012] An inverted T-shaped bottom plate fixed to the surface of the cart;

[0013] A first triangular block mounted on the left side of the cart via a hinge;

[0014] The second triangular block is hingedly mounted on the right side of the cart.

[0015] Furthermore, a carbon monoxide detection sensor is installed at the bottom of the cart in the cart system, which is connected to a controller, and the controller is connected to an alarm light installed on the shuttle bus.

[0016] Furthermore, in the cart system, a limit protection probe is provided at the end of the cart, and the limit protection probe includes:

[0017] L-shaped vertical bracket;

[0018] A Z-shaped protective head connected to an L-shaped vertical bracket via a spring.

[0019] The utility model has the following beneficial effects:

[0020] (1) Compared with existing unpowered carts, workers can directly reach the work area by riding on a cart driven by a tractor, without having to manually climb to the work site, saving time and physical effort and improving work efficiency. Compared with existing electric carts, multi-section carts driven by a tractor can transport more objects at a time, have higher work efficiency and better endurance, and can also avoid accidents caused by leakage.

[0021] (2) In addition to facilitating the passage of construction workers, this technology can also transport the stainless steel repair pipe to a designated area in the pipeline by fixing the rolled stainless steel lining pipe to a cart. When the stainless steel lining material needs to be removed and installed, it is only necessary to remove the pin at the connection of the cart and separate the connected carts to leave a construction area for laying the stainless steel lining material.

[0022] (3) When repairing stainless steel linings in confined spaces with small diameters and long distances, if a poisoning accident occurs due to harmful gas, the poisoned personnel are often unable to escape from the harmful area on their own. On-site rescue personnel are often unable to reach the trapped personnel in the first place due to wearing protective equipment and crawling long distances, thus missing out on precious rescue time. Confined space workers can connect their own safety belts to the rings at both ends of the cart during operation. If an accident occurs, the tractor can pull the power cart to rescue the trapped personnel, saving rescue time and avoiding the risk of not wearing protective equipment correctly for rescue.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0028] The first embodiment of the present invention provides a power assist system that facilitates construction workers to enter smaller diameter pipelines for construction. Figure 1 The system operates within a small-diameter pipeline 3, such as an 800mm diameter municipal pipeline. The system includes a first tractor 1 positioned at one end of the small-diameter pipeline and a second tractor 2 positioned at the other end. The number of carts in the small-diameter pipeline-compatible system 4 is selected based on construction needs, such as the six carts shown. The carts are sized to match the pipeline size, and adjacent carts are connected via detachable connectors, allowing for flexible allocation of vehicles to accommodate different construction projects. The cart system typically consists of at least two carts, one for construction workers and one for stainless steel repair materials. Two carts are used, allowing for the transport of construction materials, with four carts transporting construction materials, such as stainless steel repair materials for pipeline repair.

[0029] Continue to see Figure 1 The head trolley of the trolley system is connected to the second traction machine through a wire rope 5. Figure 1 The trolley at the middle right end is defined as the head trolley, and the trolley at the left end is defined as the tail trolley. The tail trolley of the trolley system is connected to the first traction machine through a wire rope 5. During the municipal construction process, if it is possible to excavate a working well to the horizontal height position of the municipal construction pipeline, the first traction machine and the second traction machine can be placed in the working well to realize the traction work of the trolley.

[0030] As an option, the detachable connection mechanism includes: annular joints provided at both ends of the cart, and the annular joints between adjacent carts are connected by latches. The annular joints of two adjacent carts can be connected to each other by stacking them together and inserting the latches.

[0031] The working principle of the utility model is to connect the power-assisted cart to the traction machine through a wire rope, and use the traction machine to pull the cart to the work site. Figure 1Construction workers and stainless steel repair material 6 are shown.

[0032] The second embodiment of the present invention provides a power assist system that facilitates construction workers to enter smaller diameter pipelines for construction. The difference from the first embodiment is that the tractor is installed on the ground, and a wire rope steering device is provided at the end of the small diameter pipeline. Figure 2 This figure shows a first traction machine 1 set at one end of a small-diameter pipeline and a second traction machine 2 set at the other end of the small-diameter pipeline. The first traction machine 1 is installed on the ground where the pipeline well M at one end of the small-diameter pipeline is located, and the second traction machine is installed on the ground where the pipeline well M at one end of the small-diameter pipeline is located. Wire rope steering devices are provided at the top and bottom of the pipeline well. Here, the wire rope steering device includes a top steering pulley 7 set at the top of the pipeline well and a bottom steering pulley 8 cooperated with the top steering pulley 7 and installed at the bottom of the pipeline well. The steering pulley can meet the needs of traction of the internal cart of the municipal construction pipeline.

[0033] If necessary, an operating steering wheel and steering system can be installed on the head cart to facilitate workers to appropriately adjust the forward trajectory of the cart in the pipeline.

[0034] The third embodiment of the present invention provides a power assist system that facilitates construction workers to enter smaller diameter pipelines for construction. The difference from the first or second embodiment is that the cart is installed with a temporary fixing structure that cooperates with the stainless steel repair material.

[0035] See also Figure 3 In the above-mentioned cart system, a cart is equipped with a stainless steel repair material fixing base. The stainless steel repair material fixing base includes an inverted T-shaped bottom plate 9 fixed to the surface of the cart. The inverted T-shaped bottom plate can be provided with an arc-shaped concave that matches the round stainless steel repair material. The stainless steel repair material fixing base also includes a first triangular block 10 installed on the left side of the cart via a hinge 12 and a second triangular block 11 installed on the right side of the cart via a hinge 12. When transporting, the two triangular blocks are flipped up and in a Figure 3 In the state shown, the circumferential fence can be omitted on this type of cart, but can be adapted to the circumferential fence on the cart used for transporting people. After the stainless steel repair material is transported to the repair site, the two triangular blocks are flipped outwards, and the stainless steel repair material can be removed from the cart.

[0036] The fourth embodiment of the present invention provides a power assist system that facilitates construction workers to enter smaller diameter pipelines for construction. The difference from the first embodiment is that, see Figure 4In the aforementioned cart system, a position-limiting protective probe 13 is installed at the end of the cart. This structure is intended to prevent the stainless steel repair material from moving forward due to inertia and colliding with construction workers during transportation, and can also serve as an anti-collision structure in special circumstances. Specifically, the position-limiting protective probe includes an L-shaped vertical bracket 13a welded or hinged to the surface of the cart end. The bracket can be made of metal, while the Z-shaped protective head 13b connected to the L-shaped vertical bracket via a spring 13c is the key to this structure. The end of the Z-shaped protective head can be provided with a rubber pad (5-20cm thick). The horizontal portion of the L-shaped vertical bracket can be provided with a spring guide channel, with one end of the spring fixed to the Z-shaped protective head. This allows the Z-shaped protective head to move back and forth within the spring guide channel. Under the action of external force, the tail of the Z-shaped protective head can squeeze the spring to absorb energy. During transportation, if the head of the Z-shaped protective head rests on the stainless steel repair material, the risk of accidental forward movement can be effectively avoided. In special circumstances, the position-limiting protective probe 13 installed on the lead cart can serve as an impact energy absorption structure.

[0037] A traction rod can be provided at the end of the cart (for example, a traction hook or a locking hole that can cooperate with a locking pin can be provided at the end) to cooperate with the longer limit protection probe 13 to solve the connection problem of the rear cart.

[0038] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
