Description

Technical Field

[0001] The invention belongs to the technical field of prestressed construction, and in particular relates to a steel strand pushing device with both extraction and bundle threading functions. Background Art

[0002] Prestressed concrete technology plays an important role in bridge construction, especially in the production of high-speed rail precast beams. The production process usually includes pre-embedded extraction tubes, which are made of elastic rubber and pre-embedded before pouring concrete. The function of these extraction tubes is to form prestressed channels in subsequent steps.

[0003] When the concrete is poured and reaches a certain strength, the extraction tube is pulled out to form a prestressed channel. Since the extraction tube is elastic, it is easy for the extraction tube to pop out and injure people during the extraction process. Although the current relevant construction specifications strictly prohibit the use of winches to directly pull the tube to prevent the extraction tube from popping out and causing accidents, due to the lack of mature pushing equipment technology, construction workers still use winches to pull the tubes, which poses certain safety hazards.

[0004] In addition, after the prestressed hole is formed, the steel strand bundle needs to be inserted into the hole. Existing bundle insertion equipment often uses relatively staggered semicircular slips to wrap and squeeze multiple steel strands and then push them into the hole. However, this pushing method will produce radial shear force on the steel strand bundle, which may cause damage to the hot-melt guide caps and fixed steel wires wrapped outside the steel strand bundle, or even jam the chain, affecting the efficiency and safety of bundle insertion. In addition, the radial shearing of the semicircular slips may also cause damage to the steel strand itself, affecting its performance, and thus posing a potential threat to the overall safety of the bridge.

[0005] The Chinese invention patent, named a dual-power pusher for conveying finished steel strand bundles and clamping devices, with the announcement number CN205132727U, discloses a first movable frame and a second movable frame, the first movable frame is driven to move by a lead screw pair, and the second movable frame is pushed to move by a cylinder; there are crawler transmission mechanisms on the first movable frame and the second movable frame respectively, and the first movable frame and the second movable frame can move toward the center or move to both sides at the same time, and can adjust and clamp finished steel strand bundles of different specifications. It can be seen that the dual-power pusher only has the function of clamping finished steel strand bundles of different specifications, and the operation is more troublesome when it comes to different steel strand bundle threading positions.

[0042] See also Figures 1 to 8 A steel strand pushing device with both extraction and bundle-threading functions comprises an extraction and bundle-threading composite unit 1 and a moving unit 8, wherein the extraction and bundle-threading composite unit 1 is used to clamp and extract an extraction tube or clamp and push a steel strand bundle; the extraction and bundle-threading composite unit 1 is supported by the moving unit 8, and the moving unit 8 is suitable for driving the extraction and bundle-threading composite unit 1 to move to at least one of the three directions of forward and backward, left and right, and up and down.

[0049] Bearing seats 1b are welded and fixed at both ends of the fixed beam 1i, and two bearing seats 1b are set at each end, which are respectively located on the outside of the upper and lower frames of the fixed beam 1i; a transmission shaft 1c is rotatably connected between one pair of the bearing seats 1b, and the transmission shaft 1c passes through the fixed beam 1i; a fixed shaft 1j is rotatably connected between the other pair of bearing seats 1b, and the fixed shaft 1j passes through the fixed beam 1i; one end of the transmission shaft 1c is connected to a reduction motor 1g through a coupling, and the reduction motor 1g is used to drive the transmission shaft 1c to rotate.

[0050] Bearing seats 1b are welded and fixed at both ends of the moving beam 1k, and two bearing seats 1b are set at each end, which are respectively located on the outside of the upper and lower frames of the moving beam 1k; a transmission shaft 1c is rotatably connected between one pair of the bearing seats 1b, and the transmission shaft 1c passes through the moving beam 1k; a fixed shaft 1j is rotatably connected between the other pair of bearing seats 1b, and the fixed shaft 1j passes through the moving beam 1k; one end of the transmission shaft 1c is connected to a reduction motor 1g through a coupling, and the reduction motor 1g is used to drive the transmission shaft 1c to rotate.

[0051] The transmission shaft 1c and the fixed shaft 1j on the fixed beam 1i are respectively sleeved with sprockets 1d in the circumferential outer sides, and the sprockets 1d are overlapped with chains 1e. The chains 1e are driven by the transmission shaft 1c to reciprocate between the transmission shaft 1c and the fixed shaft 1j.

[0052] The transmission shaft 1c and the fixed shaft 1j on the movable beam 1k are also sleeved with sprockets 1d on the circumferential outer sides, and a chain 1e is overlapped on the sprocket 1d. The chain 1e is driven by the transmission shaft 1c to reciprocate between the transmission shaft 1c and the fixed shaft 1j.

[0053] A number of blocks 1f are welded on the outside of the chain 1e, and a gap of 3 to 5 mm is retained between adjacent blocks 1f; the contact surface between the block 1f and the steel strand bundle or the extraction tube is provided with a concave arc surface; the block 1f arranged on the fixed beam 1i and the block 1f arranged on the movable beam 1k operate in the opposite direction, and an arc-shaped clamping channel is formed between the relatively arranged blocks 1f to clamp the steel strand bundle or the extraction tube.

[0054] The dual-purpose pushing device also includes a limiting component 2, which is arranged at both ends of the extraction and bundle-threading composite unit 1; the limiting component 2 includes limiting beams 2a arranged in pairs, and support ribs 2c are vertically welded at both ends of each pair of the limiting beams 2a, and the support ribs 2c are welded to the transverse moving frame 3a; guide wheels 2b are sleeved on the limiting beams 2a, and each pair of guide wheels 2b is used to clamp the extraction tube or the steel strand bundle.

[0055] Since the blocks 1f are arranged relative to each other, a closed channel cannot be formed between the two opposite blocks 1f. When the extraction tube is pushed, the extraction tube is an integral structure and is not affected during pushing. When pushing the steel strand bundle, since the steel strand bundle includes multiple steel strands, when the blocks 1f are clamped, there is a risk that the steel strands will be squeezed out from the upper and lower gaps, thereby affecting the pushing of the steel strand bundle. A limit assembly 2 is provided at the front and rear ends of the extraction and bundle-threading composite unit 1. The two guide wheels 2b of each limit assembly 2 and the two opposite blocks 1f can form a clamping channel projected as a nearly square, so that the steel strand bundle is clamped on all four sides during the pushing process. At the same time, since the steel strands are flexible wires with elasticity, if the clamping distance is insufficient when pushing the steel strand bundle, the steel strand bundle will bend during pushing, causing the steel strand to pop out from between the clamping blocks 1f; to avoid the above situation, the equipment adopts two sets of extraction and bundle insertion composite units 1, and limit devices 2 are installed at both ends and between the two sets of extraction and bundle insertion composite units 1 at the same time, so as to increase the clamping length of the steel strand bundle and ensure the pushing force.

[0056] The following describes the method of using the present invention:

[0057] For projects where there is no forklift on the construction site,

[0058] First, use a crane to lift the pushing device to a suitable position so that the device can smoothly perform the pulling out and threading operations;

[0059] Second, the height position of the extraction and bundle-piercing composite unit 1 is adjusted by using the vertical moving mechanism 5, the height of which is higher than the height of the extraction tube; the lifting cylinder 5b is opened, and the extension length of the telescopic end of the lifting cylinder 5b is adjusted to meet the height position of the extraction and bundle-piercing composite unit 1;

[0060] Third, the longitudinal moving mechanism 4 is used to adjust the front and rear positions of the extraction and bundle-threading composite unit 1 so that the extraction and bundle-threading composite unit 1 is aligned with the extraction tube or the steel strand bundle; the stepper motor 4d is turned on, and the stepper motor 4d drives the longitudinal moving roller 4c to move left and right along the vertical moving chassis 5b to meet the left and right positions of the extraction and bundle-threading composite unit 1;

[0061] Fourth, use the lateral moving mechanism 3 to adjust the front and rear position of the composite unit 1, so that the composite unit 1 is close to the extraction tube to be pulled out or the inserted steel strand bundle; open the lateral moving cylinder 3b, and adjust the extension length of the telescopic end of the lateral moving cylinder 3b to meet the front and rear position of the composite unit 1;

[0062] Fifth, after the dual-purpose pushing device is adjusted to a suitable position in each direction, the extraction and bundle-threading composite unit 1 clamps the extraction tube or the steel strand bundle, and pulls out the extraction tube or pushes the steel strand bundle into the prestressed channel;

[0063] Finally, after the extraction tube is extracted or the steel strand bundle is threaded into place, the extraction and threading composite unit 1 releases the clamping of the extraction tube or the steel strand bundle to complete the extraction of the extraction tube or the threading of the steel strand bundle.

[0064] For projects with forklifts on the construction site,

[0065] Place the fork of the forklift at the bottom of the longitudinal movable frame 4a, use the forklift to adjust the front and rear position and height position, and repeat the above-mentioned last three steps.
