Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction equipment, and in particular to a mobile assembly trolley for a smart beam yard. Background Art

[0002] A smart beam yard is an advanced beam yard that uses technologies such as IoT+, BIM, and informatization to achieve template automation, steel bar componentization, and intelligent concrete production. In the process of making precast beams, the smart beam yard needs to prestress the steel strands in the precast beams to make the entire precast beam have a higher bending strength. When the multiple strands in the precast beams are tensioned, an assembly trolley with tensioning function is required.

[0003] The existing assembly trolley for tensioning and pre-tightening multiple bundles of steel strands of prefabricated beams has core components including a through-type jack, a working anchor and a tool anchor. The multiple bundles of steel strands of the prefabricated beam are passed through the anchor hole of the working anchor, the through-type jack and the anchor hole of the working anchor in sequence, and each bundle of steel strands is fixed in an anchor hole of the working anchor by using a clip. Then, the through-type jack is used to apply a thrust away from the prefabricated beam to the tool anchor to simultaneously apply tensioning force to the multiple bundles of steel strands, thereby tensioning the multiple bundles of steel strands.

[0004] When using the above-mentioned precast beam assembly trolley to tension multiple bundles of steel strands on the precast beam, the steel strands inside are mainly clamped in the anchor hole of the tool anchor by the clamp. When the tool anchor is subjected to the thrust of the through-type jack, the friction between the clamp and the steel strand applies tensioning force to the steel strand. When the through-type jack tensions multiple bundles of steel strands uniformly, since the maximum static friction forces that the clamps in different anchor holes can exert on the steel strands inside are different, when the through-type jack applies a large thrust to the tool anchor, the friction force on a part of the steel strands is insufficient and they will slip relative to the clamp, resulting in uneven tensioning force on the multiple bundles of steel strands as a whole, affecting the overall tensile performance of the multiple bundles of steel strands, and thus affecting the overall strength of the bridge after assembly. Summary of the invention

[0005] The purpose of the present invention is to overcome the problems in the prior art and to provide a smart beam yard mobile assembly trolley. When using a through-type jack to tension multiple bundles of steel strands of a prefabricated beam, it can prevent a part of the steel strands from sliding relative to the anchor hole due to insufficient clamping force, thereby preventing the multiple bundles of steel strands from being subjected to uneven tensioning force during tensioning, thereby ensuring the overall tensile performance of the multiple bundles of steel strands after tensioning.

The second rotating sleeve drives the clamping mechanism to rotate, so that the tool anchor and the connecting block rotate together, thereby driving each bundle of steel strands to deflect until each bundle of steel strands remains straight, which can further ensure that each bundle of steel strands is uniformly stressed when the through-type jack tensions the steel strands, and ensure the overall tensile performance of multiple bundles of steel strands. By setting a laser transmitter to emit laser, when the light receiver receives the laser transmitted from the light hole, the power device is controlled to stop moving, so as to effectively ensure that each sliding hole is coaxial with its corresponding anchor hole, and ensure that the extrusion force applied by each sliding sleeve to the clip is the same. By controlling the rotation of the lead screw, the first nut sleeve is driven to rise or fall, and the height of the connecting block in the vertical direction is adjusted, thereby adjusting the height of each sliding sleeve until each sliding sleeve is the same height as the corresponding anchor hole, thereby effectively ensuring that each sliding hole is coaxial with the corresponding anchor hole, and ensuring that each clip can be accurately inserted into the corresponding anchor hole. By setting the maximum hydraulic threshold value, when the real-time hydraulic value in the hydraulic chamber is equal to the maximum hydraulic threshold value, the sliding sleeve can just push the clip into the anchor hole of the tool anchor, and the real-time hydraulic value in the hydraulic chamber will no longer increase, thereby preventing the sliding sleeve from applying too much extrusion force to the clip, causing the clip to clamp the steel strand and thus preventing the steel strand from breaking during tensioning.

DETAILED DESCRIPTION

[0029] The following is combined with Figure 1-Figure 6 , the specific implementation of the present invention is described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific implementation. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 6 As shown, the smart beam yard mobile assembly trolley provided by the present invention includes a lifting mechanism 102, a through-type jack 103, a working anchor 101, a tool anchor 104 and a plurality of clips 105, wherein the through-type jack 103 is used to pull multiple strands 1 through the working anchor 101, the tool anchor 104 and the plurality of clips 105, and further includes: a connecting block 106, a piston 110 and a plurality of sliding sleeves 111, wherein the connecting block 106 is arranged on the lifting mechanism 102, and a hydraulic cavity 107 is arranged on the connecting block 106, wherein the hydraulic cavity 107 is connected to a hydraulic control circuit, and a plurality of sliding holes are arranged on the side wall of the hydraulic cavity 107, wherein each sliding hole corresponds to a An anchor hole 109 of a tool anchor 104, each sliding hole is coaxially arranged with its corresponding anchor hole 109, and a clip 105 is arranged in each sliding hole; a piston 110 is slidably connected to the hydraulic chamber 107; a plurality of sliding sleeves 111 are respectively arranged in different sliding holes, and the plurality of sliding sleeves 111 are fixedly connected to the piston 110, and each sliding sleeve 111 abuts against the clip 105 at one end close to the working anchor 101, and the sliding sleeve 111 is used to apply an extrusion force to the clip 105 toward one end of the working anchor 101, and the steel strand 1 passes through the through-type jack 103, the anchor hole 109 and the clip 105, and then passes through the sleeve hole 108 of the sliding sleeve 111.

[0031] The working principle of the above embodiment is briefly described:

[0032] When the assembly trolley is in use, the lifting mechanism 102 is driven to move to the end face of the precast beam, and then the lifting mechanism 102 is controlled to move until the through-type jack 103 above the lifting mechanism 102 is on the same horizontal line with the steel strand 1, and then the working anchor 101 is put on the steel strand 1, and the working anchor 101 is abutted against the end face of the precast beam, and then the steel strand 1 is passed through the center hole of the through-type jack 103, and then the tool anchor 104 is put on the steel strand 1, one end of the through-type jack 103 is abutted against the working anchor 101, and the other end of the through-type jack 103 is abutted against the tool anchor 104, and then the clip 105 is inserted into each sliding hole on the connecting block 106, the clip 105 is abutted against the sliding sleeve 111, and the steel strand 1 is passed through the center hole of the clip 105 and the sleeve hole 108 of the sliding sleeve 111, and the connecting block 106 is connected. Block 106 presses the tool anchor 104 onto the through-type jack 103, and then controls the hydraulic control circuit to drive the piston 110 to move toward one end of the tool anchor 104. The piston 110 drives multiple sleeves 111 to move toward one end of the tool anchor 104, and each sleeve 111 pushes the clip 105 abutting against it toward the anchor hole 109 corresponding to the sleeve 111 until the sleeve 111 presses each clip 105 into the anchor hole 109, which can improve the clamping effect of the tool anchor 104 on the steel strand 1, so that each bundle of steel strand 1 can be clamped in the anchor hole 109 of the tool anchor 104 by the clip 105, so that when the through-type jack 103 tensions the steel strand 1, it prevents the multiple bundles of steel strands 1 from being subjected to uneven force, resulting in different tensioning forces on the multiple bundles of steel strands 1, thereby affecting the overall tensile performance of the multiple bundles of steel strands 1.

[0033] The intelligent beam yard mobile assembly trolley of the present invention can uniformly apply the same extrusion force toward the anchor hole 109 of the tool anchor 104 to the multiple clips 105 when using the through-type jack 103 to tension the multiple bundles of steel strands 1 of the prefabricated beam, so that the compaction degree of each clip 105 in the anchor hole 109 is the same, so that the maximum static friction force that each clip 105 can apply to the steel strand 1 therein is the same. When the through-type jack 103 tensions the steel strand 1, a part of the steel strand 1 is prevented from slipping relative to the clip 105 due to insufficient friction of the clip 105, thereby preventing uneven tensioning force on the multiple bundles of steel strands 1 as a whole, and avoiding affecting the overall tensile performance of the multiple bundles of steel strands 1 due to different tensioning forces on the multiple bundles of steel strands 1 as a whole.

[0034] On the basis of the above embodiments, in order to ensure that the sliding sleeve 111 can accurately push the clip 105 into the anchor hole 109, the normal operation of the entire assembly trolley is ensured.

[0035] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the connecting block 106 is provided with a shell 201, and the shell 201 is connected to the lifting mechanism 102. The connecting block 106 is provided with a first rotating sleeve 202, and the first rotating sleeve 202 is pivotally connected to the shell 201. The outer wall of the first rotating sleeve 202 is provided with a tooth block 203, and the tooth block 203 is toothed with a power device, and the power device is used to drive the connecting block 106 to rotate around the axis of the tool anchor 104 through the first rotating sleeve 202.

[0036] After the steel strand 1 passes through the through-type jack 103, the anchor hole 109, the clip 105 and the sleeve hole 108 of the sleeve 111, the power device is used to drive the tooth block 203 to rotate around the axis of the tool anchor 104, thereby driving the first rotating sleeve 202 to rotate, and the first rotating sleeve 202 drives the connecting block 106 to rotate around the axis of the tool anchor 104 to adjust the position of the sliding hole on the connecting block 106 relative to the anchor hole 109 on the tool anchor 104, so as to ensure that the sliding hole is coaxial with the anchor hole 109, to ensure that each sliding hole is coaxial with its corresponding anchor hole 109, to ensure that each sleeve 111 applies the same extrusion force to the clip 105, thereby ensuring that each clip 105 can apply the same maximum static friction force to the steel strand 1 therein, and effectively ensuring that each bundle of steel strands 1 is subjected to the same tension force.

[0037] As a preferred solution, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a second rotating sleeve 301 is provided at one end of the shell 201 close to the tool anchor 104, and the second rotating sleeve 301 is pivotally connected to the shell 201. A gear ring 302 is provided outside the second rotating sleeve 301. The power device is connected to a clutch, and the power device is gear-connected with the gear ring 302 through the clutch. A clamping mechanism 303 is connected to the second rotating sleeve 301, and the clamping mechanism 303 is used to clamp the tool anchor 104. The power device is used to drive the tool anchor 104 to rotate around the axis of the tool anchor 104 through the second rotating sleeve 301 and the clamping mechanism 303. When the anchor hole 109 is coaxial with the sliding hole, the clutch is controlled to operate so that the power device is engaged with the gear ring 302, the power device drives the tooth block 203 and the gear ring 302 to rotate together, the gear ring 302 drives the second rotating sleeve 301 to rotate, the second rotating sleeve 301 drives the clamping mechanism 303 to rotate, the clamping mechanism 303 drives the clamped tool anchor 104 to rotate, so that the tool anchor 104 and the connecting block 106 rotate together, thereby driving each bundle of steel strands 1 to deflect until each bundle of steel strands 1 remains straight, which can further ensure that each bundle of steel strands 1 is subjected to uniform force when the through-type jack 103 tensions the steel strands 1, thereby ensuring the overall tensile strength of the multiple bundles of steel strands 1.

[0038] As a preferred solution, Figure 2-Figure 5As shown, a positioning groove 401 is provided on the outer wall of the tool anchor 104, a positioning block 402 is provided on the clamping mechanism 303, and the positioning block 402 is clamped in the positioning groove 401. A light-through hole 403 is provided on the tooth block 203, and the length direction of the plurality of light-through holes 403 is the same as the axial direction of the tool anchor 104. The gear ring 302 is provided on one side of the light-through hole 403, and a light receiver 404 is provided on the gear ring 302. A laser emitter 405 is provided on the other side of the light-through hole 403. The light emitted by the laser emitter 405 can pass through the light-through hole 403 and be received by the light receiver 404. Under the positioning action of the positioning block 402, when the light receiver 404 receives the laser emitted by the laser emitter 405, each sliding hole is coaxial with the corresponding anchor hole 109. The second rotating sleeve 301 rotates around the axis of the tool anchor 104 under the drive of the gear ring 302, thereby driving the clamping mechanism 303 to rotate. The clamping mechanism 303 drives the tool anchor 104 to rotate through the positioning block 402 and the positioning groove 401. The positioning block 402 and the positioning groove 401 can prevent the tool anchor 104 from rotating relative to the clamping mechanism 303. In this process, the laser emitted by the laser transmitter 405 passes through the light hole 403 and is projected onto the gear ring 302. As the gear ring 302 rotates, the gear ring 302 drives the light receiver 404 thereon to rotate until the light receiver 404 receives the laser transmitted from the light hole 403, and the control power device stops the action, thereby effectively ensuring that each sliding hole is coaxial with its corresponding anchor hole 109, and ensuring that each sliding sleeve 111 applies the same extrusion force to the clip 105.

[0039] As a preferred solution, Figure 1-Figure 5 As shown, a frame 601 is provided at the top of the lifting mechanism 102, and a vertical screw 602 and a slide rail 604 are provided in the frame 601. The screw 602 is pivotally connected to the frame 601, and a first nut sleeve 603 and a slider 605 are provided on the outer shell 201. The first nut sleeve 603 is pivotally connected to the screw 602, and the slider 605 is slidably connected to the slide rail 604. By controlling the rotation of the lead screw 602, the first nut sleeve 603 is driven to rise or fall, and the first nut sleeve 603 drives the housing 201 to rise or fall. The housing 201 slides on the slide rail 604 through the slider 605, so that the height of the housing 201 can be adjusted, thereby adjusting the height of the connecting block 106 in the vertical direction, thereby adjusting the height of each sliding sleeve 111, until each sliding sleeve 111 is the same height as its corresponding anchor hole 109, thereby effectively ensuring that each sliding hole is coaxial with its corresponding anchor hole 109, and ensuring that each clip 105 can be accurately inserted into its corresponding anchor hole 109.

By setting the hydraulic sensor 5, when the hydraulic control circuit passes hydraulic oil into the hydraulic chamber 107 to drive the piston 110 to move, the hydraulic sensor 5 is used to detect the real-time hydraulic value in the hydraulic chamber 107. The real-time hydraulic value in the hydraulic chamber 107 and the pressure area of ​​the piston 110 can be used to know the magnitude of the hydraulic thrust on the piston 110, so that the magnitude of the extrusion force applied by each sleeve 111 to the clamp 105 abutting therewith can be known. By setting the magnitude of the maximum hydraulic threshold, when the real-time hydraulic value in the hydraulic chamber 107 is equal to the maximum hydraulic threshold, the sleeve 111 can just push the clamp 105 into the anchor hole 109 of the tool anchor 104. At this time, the controller controls the hydraulic control circuit to stop the action, and the hydraulic control circuit stops supplying hydraulic oil to the hydraulic chamber 107. The real-time hydraulic value in the hydraulic chamber 107 no longer increases, thereby preventing the sleeve 111 from applying too much extrusion force to the clamp 105, causing the clamp 105 to clamp the steel strand 1, thereby preventing the steel strand 1 from breaking during tensioning.

[0041] As a preferred solution, Figure 1 As shown, the lifting mechanism 102 includes a telescopic frame 801 and a screw 802, the bottom end of the telescopic frame 801 is connected to the vehicle body 804, the top of the telescopic frame 801 is connected to the through-type jack 103 and the frame 601, and a second nut sleeve 803 is provided on the telescopic frame 801. The screw 802 is horizontally arranged and pivotally connected to the vehicle body 804, and the screw 802 is threadedly connected to the second nut sleeve 803.

By rotating the screw rod 802, the second nut sleeve 803 on the screw rod 802 is driven to move, thereby driving the telescopic frame 801 to extend or contract, thereby accurately controlling the lifting and lowering of the lifting mechanism 102, thereby accurately controlling the height of the first electric slide rail 7, and adjusting the vertical height of the through-type jack 103 and the connecting block 106, so as to tension the steel strands 1 of different heights of the prefabricated beam, thereby improving the applicability of the assembly trolley.
