Description

Technical Field

[0001] The utility model relates to the technical field of socket-and-spigot type pipeline installation, in particular to a socket-and-spigot type chemical building material pipe connection auxiliary device, which is especially suitable for polyethylene double-wall corrugated pipes. Background Art

[0002] As the underground pipeline network ages, it needs large-scale renovation.

[0003] In the prior art, for buried plastic drainage pipes, when the spigot is inserted into the socket, a wooden baffle can be set at the end of the small-diameter pipe, and the pipe can be slowly inserted into the socket along the axis with a crowbar; for pipes with a nominal diameter greater than DN400, a cable can be used to tie the pipe, and the pipe can be slowly pulled into the socket with tools such as a hand hoist.

[0004] For socket-type flexible interface connections, it is advisable to carry out the connection when the temperature is higher on the day. The spigot end should not be inserted to the bottom of the socket, and a expansion gap of not less than 10mm should be left.

[0005] In the prior art, it is usually installed by manpower, with the help of simple tools, pushing on one side of the pipe and pulling on the other side. The disadvantages of the above existing installation methods are obvious:

[0006] First, the operators are very tired and physically exhausted, especially in the trench (where the operating space is limited), which will affect the installation quality over time;

[0007] Secondly, it is difficult to control the expansion gap between the plug end and the bottom of the socket, which may cause the plug to be inserted too deeply or not fully inserted, thus affecting the result of the water-tightness test.

[0008] Third, even if the water-tightness test is passed at present, there is still the hidden danger of water leakage in the future, which may cause greater trouble.

[0009] Therefore, how to improve the efficiency of the socket-and-spigot construction of the socket-and-spigot pipe, reduce the construction intensity and improve the construction accuracy has become a technical problem that technical personnel in this field need to solve urgently.

[0043] Example

[0044] like Figures 1 to 5 As shown, a specific embodiment of the socket-and-spigot type chemical building material pipe connection auxiliary device of the utility model is used to assist the socket-and-spigot connection construction of a first horizontal pipe 1 and a second horizontal pipe 2 connected in a socket-and-spigot manner, comprising two towing ropes 3 sleeved on the first horizontal pipe 1 and the second horizontal pipe 2 near the socket position, and a tightening mechanism 8 arranged above the first horizontal pipe 1 and the second horizontal pipe 2 and located between the two towing ropes 3;

[0045] The tightening mechanism 8 is connected to the towing rope 3 arranged on the first horizontal pipeline 1 through the first hook 4, and is connected to the towing rope 3 arranged on the second horizontal pipeline 2 through the second hook 5.

[0046] The tightening mechanism 8 has a mechanical structure inside that can reduce or enlarge the distance between the first hook 4 and the second hook 5. The distance between the first hook 4 and the second hook 5 is tightened by the mechanical structure to drag the first horizontal pipe 1 and the second horizontal pipe 2 axially together to form a socket connection.

[0047] In actual application, after the utility model is installed, the installation fixation and safety protection of the utility model are first checked. During the process of connecting the pipelines, the construction personnel place the utility model on one side of the first horizontal pipeline 1 or the second horizontal pipeline 2 with a socket, and connect it to the two towing ropes 3 through the first hook 4 and the second hook 5.

[0048] After the connection is completed, the two towing ropes 3 are sleeved with the connection between the first horizontal pipeline 1 and the second horizontal pipeline 2.

[0049] After the socket connection is completed, the first horizontal pipeline 1 and the second horizontal pipeline 2 are connected. The construction personnel tighten the distance between the first hook 4 and the second hook 5 through the mechanical structure, so that the first horizontal pipeline 1 or the second horizontal pipeline 2 socketed by the towing rope 3 is connected, thereby completing the socket connection between the first horizontal pipeline 1 or the second horizontal pipeline 2.

[0050] In some embodiments, the mechanical structure includes a pair of meshing gears and a limit block; specifically, the two meshing gears are connected to the two hooks through two sections of wire ropes, and the wire rope is wound around the wire groove 501 through the guide wheel 4 and the slot 502. During the process of the wire rope being subjected to force, the wire rope can be restricted, so that the wire rope is not easily displaced and will not affect the stretching of the pipeline.

[0051] Each gear is connected to the housing 81 of the tightening mechanism 8 by a corresponding rotary shaft to form a rotary pair;

[0052] Each rotating shaft or the second hook 5 is connected by a steel wire rope 7. When rotating, the corresponding steel wire rope 7 can be wound and rolled to tighten the distance between the first hook 4 and the second hook 5.

[0053] Each gear is connected to the rotary power input shaft 83 through a mechanical transmission chain, and receives the torque received by the rotary power input shaft 83 to rotate;

[0054] The limit block is used to lock all gears so that they cannot rotate.

[0055] In some other embodiments, the mechanical structure may include a winch gear and a limit block; specifically, a single winch gear is connected to a hook via a section of wire rope, and another hook is arranged on the outer shell 81. The wire rope is wound around the steel wire groove 501 through the guide wheel 4 and the slot 502. During the process of the wire rope being subjected to force, the wire rope can be restricted, so that the wire rope is not easily displaced and does not affect the stretching of the pipeline.

[0056] The winch gear and the housing 81 of the tightening mechanism 8 are connected to each other through corresponding rotary shafts to form a rotary pair;

[0057] The rotating shaft of the hoisting gear is connected to the first hook 4 or the second hook 5 which is closest to it by a section of wire rope 7, and the remaining second hook 5 or the first hook 4 is fixedly connected to the side of the housing 81 which is away from the wire rope 7;

[0058] When the winch gear rotates, it can wind the corresponding steel wire rope 7 into a roll to tighten the distance between the first hook 4 and the second hook 5;

[0059] The hoisting gear is connected to the rotary power input shaft 83 through a mechanical transmission chain, and receives the torque received by the rotary power input shaft 83 to rotate;

[0060] The limit block is used to lock the winch gear so that it cannot rotate.

[0061] In some embodiments, a pulley is provided between the second hook 5 and the corresponding wire rope 7;

[0062] The steel wire rope 7 is wound around the corresponding pulley to form a movable pulley.

[0063] In some embodiments, the mechanical transmission chain is disposed on a tubular drive arm 82;

[0064] One end of the driving arm 82 is connected to the housing 81, and the other end is provided with a rotation power input shaft 83;

[0065] One end of the rotary power input shaft 83 extends from the side wall of the driving arm 82 and is connected to an "L"-shaped rotary rod 84;

[0066] The user gripping portion of the "L"-shaped rotating rod 84 is wrapped with a layer of non-slip rubber pad.

[0067] In practical applications, the setting of the "L"-shaped rotating rod 84 forms a lever arm, which enables construction workers to rotate better during operation. The anti-slip rubber pad can effectively enhance the friction of the operator's hand, making it easier for construction workers to operate.

[0068] In some embodiments, the mechanical transmission chain is as follows: a rotating wheel 601, a driving rod 602 and a driving gear 603 are provided inside the driving arm 82, the rotating wheel 601 and the driving gear 603 are connected through the driving rod 602, and a rotating power input shaft 83 is clamped on the outer side of the rotating wheel 601.

[0069] By using the rotating wheel 601, construction workers can better assist in rotation during operation.

[0070] The construction personnel rotate the grip 84, which will drive the internal rotating wheel 601 to rotate during the rotation, so that the driving rod 602 rotates the driving gear 603, and the driving gear 603 will mesh with the lifting gear, driving the lifting gear to rotate, transmitting power, and their rotation directions are opposite. The lifting gear will amplify the external force, and the steel wire rope of the steel wire groove 501 will be recovered during the rotation of the lifting gear. The recovered steel wire rope will slide through the guide wheel, driving the hook 9 of the traction mechanism 6 to stretch, so that the pipe connected by the rope is connected to the main pipe, thereby completing the socket connection between the pipes.

[0071] In some embodiments, the first hook 4 or the second hook 5 includes a hook body 9 and an elastic anti-slip sheet 92 connected to a root 91 of the hook body 9 in a swivel pair;

[0072] A plurality of elastic barbs 93 are provided on the concave side of the hook body 9 along the length direction of the bend;

[0073] The length of each elastic barb 93 protruding from the concave side of the hook body 9 can meet the requirements of the elastic anti-slip sheet 92 of the card holder.

[0074] In actual application, during the connection between the towing rope 3 and the hook body 9, the hook body 9 can be closed by the elastic anti-slip sheet 92, thereby preventing the towing rope 3 from accidentally slipping out and affecting the installation of the first horizontal pipe 1 or the second horizontal pipe 2.

[0075] In practical applications, each towing rope 3 is a nylon rope with a length of 180 cm and a diameter of 3 cm.

[0076] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
