Abstract
Description
Technical Field
[0001] This utility model belongs to the field of concrete pipe technology, and in particular relates to a concrete pipe with a pre-embedded hoisting hole. Background Technology
[0002] In the construction and laying of concrete pipes, the hoisting and positioning of the pipes are critical aspects affecting project efficiency and safety. Traditional concrete pipes typically lack dedicated hoisting points, requiring ropes to be wrapped around the pipe or external clamps for fixation during hoisting. This method is not only cumbersome and time-consuming, but also prone to localized damage to the pipe ends due to stress concentration. During hoisting, the pipes are prone to rolling or slipping, posing safety hazards. Furthermore, the lack of standardized hoisting interfaces means that hoisting tools are not interchangeable, and repeated hoisting operations may cause wear on the pipe surface, affecting its service life and sealing performance. Fine-tuning after the pipes are in place often lacks effective auxiliary structures, making it difficult to achieve precise alignment.
[0003] To address these issues, we provide a concrete pipe with pre-embedded lifting holes. Utility Model Content
[0004] The purpose of this utility model is to provide a concrete pipe with pre-embedded lifting holes. By fitting two pipe supports on the outer side of the lower end of the pipe body, the lower plane of the pipe supports is placed on the ground when the pipe body is buried, so that the pipe does not roll horizontally. By fixing and installing lifting ears on both ends of the upper surface of the pipe supports, before placing the pipe body into the pipe base, the lifting rope is first passed through the lifting holes on each lifting ear, and then the crane lifts the lifting rope, raises the pipe support and sends it into the pipe base, thereby transferring the pipe body into the pipe base.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a concrete pipe with pre-embedded lifting holes, including a pipe body and two pipe supports. The pipe supports are square structures with semi-cylindrical grooves on the upper end face. The semi-cylindrical grooves at the upper end of the pipe supports penetrate through both end faces of the pipe supports. The pipe body is sleeved in the upper semi-cylindrical grooves of the two pipe supports. Lifting ears are fixedly installed at both ends of the upper end face on both sides of the pipe supports, and lifting holes are opened through the sides of the lifting ears.
[0006] A further feature of this invention is that steel strips are fixedly installed at both ends of the inner side of the pipe support. The steel strips have a semi-circular arc structure and are fixedly attached to the inner wall of the semi-cylindrical groove of the pipe support. The two ends of the steel strips are fixedly connected to the lifting lugs on both sides.
[0007] A further feature of this invention is that a set of spring channels are vertically opened on the lower end face of the tube support, a buffer rod is slidably sleeved in the spring channels, and a buffer spring is sleeved in the spring channels. The two ends of the buffer spring are respectively fixedly connected to the inner top surface of the spring channels and the upper end face of the buffer rod.
[0008] A further feature of this invention is that a contact plate is provided below the tube support, and the lower end face of each buffer rod is fixedly connected to the upper end face of the contact plate below.
[0009] A further feature of this invention is that two side sliding flanges are axially arrayed and fixed on both sides of the outer wall of the pipe body, and side sliding grooves are respectively opened on both sides of the inner wall of the pipe support. The two side sliding flanges are horizontally slidably sleeved in the side sliding grooves on both sides of the inner wall of the two pipe supports.
[0010] A further feature of this invention is that a set of hemispherical grooves are provided at the lower end of the side sliding flange, and receiving balls are rolled and installed in the hemispherical grooves on the lower end face of the side sliding flange. A ball groove is provided on the bottom surface of the side sliding groove, and the length direction of the ball groove is parallel to the length direction of the tube body. The receiving balls are nested in the ball groove.
[0011] A further feature of this invention is that two ball bearing platforms are axially arrayed and fixed on the lower outer end face of the tube body. A set of hemispherical grooves is opened on the lower end face of the ball bearing platforms. Receiving balls are rolled in the hemispherical grooves on the lower end face of the ball bearing platforms. A transverse sliding groove is opened on the lower end of the inner wall of the tube support. The length direction of the transverse sliding groove is parallel to the length direction of the tube support. The receiving balls on the lower end face of the ball bearing platforms are pressed in the transverse sliding groove.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1 Please see Figures 1 to 3 This utility model is a concrete pipe with pre-embedded lifting holes, including a pipe body 1 and two pipe supports 2. By fitting two pipe supports 2 on the outer side of the lower end of the pipe body 1, the lower plane of the pipe support 2 is placed on the ground when the pipe body 1 is buried, so that the pipe does not roll horizontally. By fixing and installing lifting ears 201 on both sides of the upper end face of the pipe support 2, before placing the pipe body 1 into the pipe base, the lifting rope is first passed through the lifting hole 201a on each lifting ear 201, and then the lifting rope is lifted by the crane, the pipe support 2 is raised and sent into the pipe base, thereby transferring the pipe body 1 into the pipe base.
[0023] Specifically, the pipe support 2 is a block structure with a semi-cylindrical groove on the upper end face. The semi-cylindrical groove at the upper end of the pipe support 2 passes through both ends of the pipe support 2. The pipe body 1 is sleeved in the upper semi-cylindrical groove of the two pipe supports 2. Lifting ears 201 are fixedly installed at both ends of the upper end face on both sides of the pipe support 2. Lifting ears 201 have lifting holes 201a through the side.
[0024] Furthermore, steel strips 202 are fixedly installed at both ends of the inner side of the pipe support 2. The steel strips 202 have a semi-circular arc structure and are fixedly attached to the inner wall of the semi-cylindrical groove of the pipe support 2. The two ends of the steel strips 202 are fixedly connected to the lifting lugs 201 on both sides. The steel strips 202 are used to support the weight of the pipe body 1 and prevent the pipe support 2 from being over-stressed during the lifting of the pipe body 1, which would cause the pipe support 2 to break.
[0025] Furthermore, a set of spring channels 203 is vertically opened on the lower end face of the tube support 2. A buffer rod 203a is slidably sleeved in the spring channel 203. A buffer spring 203a-1 is sleeved in the spring channel 203. The two ends of the buffer spring 203a-1 are respectively fixedly connected to the inner top surface of the spring channel 203 and the upper end face of the buffer rod 203a.
[0026] Furthermore, a contact plate 203b is provided below the pipe support 2. The lower end face of each buffer rod 203a is fixedly connected to the upper end face of the contact plate 203b below. When the pipe support 2 is placed on the pipe base, the contact plate 203b contacts the ground first. The weight of the pipe body 1 and the pipe support 2 causes the buffer rod 203a to compress the buffer spring 203a-1, thereby allowing the buffer spring 203a-1 to absorb the downward impact force of the pipe body 1 and the pipe support 2, preventing the pipe body 1 from breaking due to excessive impact.
[0027] The operation process in this embodiment is as follows: The hoisting rope is passed through the hoisting holes 201a on each hoisting lug 201, and the two pipe supports 2 are lifted by the crane and transferred to the pipe base. When the pipe supports 2 are placed on the pipe base, the contact floor 203b contacts the ground first. The weight of the pipe body 1 and the pipe support 2 causes the buffer rod 203a to compress the buffer spring 203a-1, thereby absorbing the downward impact force of the pipe body 1 and the pipe support 2, preventing the pipe body 1 from breaking due to excessive impact.
[0028] Example 2 Please see Figures 1 to 5 Based on embodiment 1, two side sliding flanges 101 are axially arrayed and fixed on both sides of the outer wall of the pipe body 1, and side sliding grooves 204 are respectively opened on both sides of the inner wall of the pipe support 2. By horizontally sliding the side sliding flanges 101 on both sides into the side sliding grooves 204 on both sides of the inner wall of the two pipe supports 2, the pipe support 2 is placed on the pipe base, and the pipe body 1 is pushed to move, so that one end of the pipe body 1 is connected to one end of another pipe body 1 on the pipe base, so that the two pipe bodies 1 are connected to each other.
[0029] Specifically, the two side sliding flanges 101 are horizontally slidably sleeved in the side sliding grooves 204 on both sides of the inner wall of the two pipe supports 2.
[0030] Furthermore, a set of hemispherical grooves is provided at the lower end of the side sliding flange 101. A receiving ball 102 is rolled in the hemispherical grooves on the lower end face of the side sliding flange 101. A ball groove 204a is provided on the bottom surface of the side sliding groove 204. The length direction of the ball groove 204a is parallel to the length direction of the pipe body 1. The receiving ball 102 is nested in the ball groove 204a. The side sliding flange 101 is sleeved in the side sliding groove 204 to prevent the pipe body 1 from rolling and rotating in the pipe support 2.
[0031] Furthermore, two ball bearing platforms 103 are axially arrayed and fixed on the lower outer end face of the tube body 1. A set of hemispherical grooves is opened on the lower end face of the ball bearing platform 103. The receiving ball bearing 102 is rolled in the hemispherical groove on the lower end face of the ball bearing platform 103. A transverse sliding groove 205 is opened on the lower end of the inner wall of the tube support 2. The length direction of the transverse sliding groove 205 is parallel to the length direction of the tube support 2. The receiving ball bearing 102 on the lower end face of the ball bearing platform 103 is pressed in the transverse sliding groove 205.
[0032] The operation process in this embodiment is as follows: After placing the two pipe supports 2 on the pipe base, push the pipe body 1 to move axially, so that the pipe body 1 connects with one end of another pipe body 1 on the pipe base; when pushing the pipe body 1 to move, the balls at the lower end of the side sliding flange 101 and the lower end of the ball bearing platform 103 roll, reducing the friction when the pipe body 1 moves, making the movement of the pipe body 1 more effortless.
