DETAILED DESCRIPTION

[0024] In order to make the utility model more obvious and easy to understand, the following will be combined with the drawings in the embodiment of the utility model, and the technical scheme in the embodiment of the utility model will be clearly and completely described.

[0025] Specific embodiment one: combined Figures 1 to 6 It is explained that the moving device for installing the box culvert template includes a hydraulic oil cylinder 100, a telescopic support leg 200, a crossbeam 300, a steering unit 400, a one-way walking mechanism 500 and a manual hydraulic pump 600.

[0027] The manual hydraulic pump 600 is connected with the hydraulic oil cylinder 100 through a pipeline, the cylinder body of the hydraulic oil cylinder 100 is installed at the top of the outer cylinder 210, the two ends of the inner cylinder 220 are fixedly connected with the crossbeam 300 and the telescopic rod of the hydraulic oil cylinder 100 respectively, and the crossbeam 300 is arranged horizontally.

[0028] The steering unit 400 includes a steering disc 410, a steering shaft 420, a stepped positioning shaft 430 and a locking seat 440.

[0029] Four positioning grooves 411 are equiangularly arranged on the circumferential surface of the steering disc 410, and the upper surface of the steering disc 410 is coaxially fixedly connected with the steering shaft 420.

[0030] The steering shaft 420 is rotationally connected with the crossbeam 300, the locking nut 421 and the thrust bearing 422 are installed on the steering shaft 420, the locking nut 421 and the thrust bearing 422 are arranged on the two side surfaces of the crossbeam 300 respectively, and the two end surfaces of the thrust bearing 422 are respectively abutted with the steering disc 410 and the crossbeam 300.

[0031] The locking seat 440 is fixedly connected with the cross beam 300, the stepped positioning shaft 430 is slidably connected with the locking seat 440, and one end of the stepped positioning shaft 430 is inserted into the positioning groove 411.

[0032] The one-way walking mechanism 500 is fixedly connected to the lower surface of the steering disc 410.

[0033] Specific implementation method two: combined Figures 1 to 6 In this embodiment, the stepped positioning shaft 430 includes a first shaft body, a shaft ring and a second shaft body which are integrally arranged in sequence along the length direction of the stepped positioning shaft 430.

[0034] The second shaft body is inserted into the positioning groove 411, the first shaft body is slidably connected with the locking seat 440, and the compression spring 431 is sleeved on the first shaft body, and the two ends of the compression spring 431 are respectively abutted against the locking seat 440 and the shaft ring.

[0035] Further, the steering principle of the steering unit 400 is that the upper surface of the steering disc 410 is coaxially fixedly connected with the steering shaft 420, the steering shaft 420 is rotatably connected with the cross beam 300, and because the one-way walking mechanism 500 is fixedly connected to the lower surface of the steering disc 410, the second shaft body is pulled out from the current positioning groove 411, the steering shaft 420 is rotated by 90°, 180° or 270°, and then the walking direction of the one-way walking mechanism 500 can be changed, and after the walking direction is changed, the stepped positioning shaft 430 is re-inserted into other positioning grooves 411 under the spring force of the compression spring 431.

[0036] The other components and connection relationships are the same as those in the specific implementation method one.

[0037] Specific implementation method three: combined Figures 1 to 6 In this embodiment, the one-way walking mechanism 500 includes a support frame 510, a roller 520 and a rotating shaft 530.

[0038] The support frame 510 is fixedly connected with the lower surface of the steering disc 410, and the side vertical surface of the support frame 510 is provided with a ratchet claw 511, the roller 520 is coaxially fixedly connected with the rotating shaft 530, and the roller 520 is circumferentially fixed on the rotating shaft 530 through a flat key, the rotating shaft 530 is rotatably connected with the support frame 510, and the rotating shaft 530 is coaxially provided with a ratchet wheel 501 matched with the ratchet claw 511.

[0039] In this embodiment, through the steering effect of the steering unit 400, the one-way walking mechanism 500 can have four walking directions, and the specific principle is that:

[0040] The upper surface of the steering disc 410 is coaxially fixed with a steering shaft 420, and the steering shaft 420 is rotationally connected with the cross beam 300. Since four positioning grooves 411 are equiangularly arranged on the steering disc 410, and the line connecting the first positioning groove 411 and the third positioning groove 411 is parallel to the rotation axis of the roller 520, and the line connecting the second positioning groove 411 and the fourth positioning groove 411 is perpendicular to the rotation axis of the roller 520, the walking direction of the unidirectional walking mechanism 500 can be ensured to be towards the advancing or retreating direction of the box culvert template, or towards the direction of the box culvert template approaching or moving away from the embedded bar.

[0041] In this way, by using the characteristics of the ratchet and pawl unidirectional transmission, the movement of the box culvert template during the advancing or fine adjustment process due to the uneven ground of the construction site can be avoided. For example, if the advancing direction of the box culvert template is uphill, the walking direction of the unidirectional walking mechanism 500 is kept the same as the advancing direction of the box culvert template, and by using the characteristics of the unidirectional transmission, the box culvert template can be prevented from retreating. For example, if the advancing direction of the box culvert template is downhill, the walking direction of the unidirectional walking mechanism 500 is kept opposite to the advancing direction of the box culvert template, at this time, the roller 520 cannot rotate due to the characteristics of the ratchet and pawl unidirectional transmission, and the box culvert template cannot move. Therefore, the ratchet and pawl need to be slowly manually controlled to engage, and only when the pawl 511 is disengaged from the ratchet 501, the roller 520 can continue to rotate. In this way, the box culvert template can be prevented from advancing rapidly.

[0042] When the box culvert template approaches or moves away from the embedded bar, the walking direction of the unidirectional walking mechanism 500 can be changed by the steering unit 400, so that the walking direction is towards or away from the embedded bar. The specific movement principle is the same as the above process.

[0043] The other components and connection relationships are the same as those in the first or second embodiment.

[0044] The fourth embodiment is combined with the first embodiment. Figures 1 to 6 In this embodiment, the cross beam 300 is a channel steel.

[0045] Further, the outer cylinder 210 and the inner cylinder 220 are both hollow steel pipes.

[0046] Further, the end of the steering shaft 420 is integrally provided with a hexagonal screwing part. In this way, the worker can rotate the steering shaft 420 by using a wrench and the screwing part, which facilitates steering.

[0047] Further, the support frame 510 is connected with the steering disc 410 by welding.

[0048] The other components and connection relationships are the same as those in the first, second or third embodiment.

[0049] Working principle

[0050] Combining Figures 1 to 6 The working principle of the utility model is explained in combination with the operation steps of the box culvert template during the transfer:

[0051] Step one, fix the hydraulic cylinder 100 on the box culvert template, process a through hole on the steel vertical beam of the box culvert template, and install the nut after the stud 211 on the outer cylinder 211 passes through the through hole, so as to fix the outer cylinder 211 on the steel vertical beam, and install several utility models on one box culvert template.

[0052] Step two, twist the steering shaft 420 according to the ground condition of the construction site, and then control the walking direction of the one-way walking mechanism 500, for example, if the advancing direction of the box culvert template is uphill, the walking direction of the one-way walking mechanism 500 is kept the same as the advancing direction of the box culvert template, then the one-way transmission characteristic can prevent the box culvert template from reversing; if the advancing direction of the box culvert template is downhill, the walking direction of the one-way walking mechanism 500 is kept opposite to the advancing direction of the box culvert template, then slowly manually control the ratchet engagement of the ratchet and pawl, which can prevent the box culvert template from advancing rapidly.

[0053] Step three, hoist the box culvert template to the entrance of the box culvert, slowly lower it, make the roller 520 touch the ground, and move the box culvert template to the designated position by manpower or tractor traction, during which the top of the box culvert template abuts against the box culvert side wall embedded bar, so that the box culvert template can stand and move.

[0054] Step four, after the box culvert template moves to the designated position, first change the walking direction of the one-way walking mechanism 500 through the steering unit 400, so that the box culvert template can approach or move away from the box culvert side wall embedded bar, and then adjust the distance between the box culvert template and the box culvert side wall embedded bar.

[0055] Then slowly release the hydraulic cylinder 100, so that the box culvert template falls to the ground, and at the same time, observe whether the splicing joint between the current box culvert template and the previous box culvert template is uniform, if not, adjust the extension amount of the telescopic supporting leg 200 through the cooperation of the manual hydraulic pump 600 and the hydraulic cylinder 100, so that the current box culvert template is slightly lifted, and then place a cushion block at the bottom thereof, so as to ensure the uniformity of the joint, and avoid the situation that the top and bottom of the joint have different widths, causing concrete leakage or uneven surface after the concrete hardens.

[0056] Finally, after fixing the box culvert template, the utility model is disassembled from the current box culvert template in sequence, and the installation of the next template is continued.

[0057] The utility model has disclosed the above with preferable implementation, however is not used to limit the utility model, any familiar professional technical personnel, does not depart from the content of the utility model technical scheme, according to the technical essence of the utility model to the above implementation case of any simple modification, equivalent change and modification, still belong to the utility model technical scheme range.
