Description

Technical Field

[0001] The present invention relates to the field of slope protection, and in particular to a slope concrete spraying device and a construction method thereof. Background Art

[0002] During the construction of a connected channel, if the stability of the slope rock stratum is poor and it is prone to local collapse and deformation along the weak structural plane, and there are safety risks such as slope collapse and falling from a height, the method of "step blasting + breaker excavation" is usually adopted to form a flat and stable stepped slope. At the same time, after each step is formed, ecological concrete is sprayed in a timely manner to construct an effective slope protection system.

[0003] However, at present, the spraying operation of ecological concrete mainly relies on manual operation: workers need to hold the spray pipe and stand on the elevated rack to spray the slope section by section. Due to the limitations of the operation height and the physical strength of workers, the spraying range is limited. Especially in the long-distance area, the concrete is prone to divergence and splashing, resulting in material waste. In addition, to ensure the spraying quality and coverage continuity, workers need to operate continuously and stably, with high labor intensity, low efficiency, and the construction quality is greatly affected by human factors, resulting in high overall construction costs and difficult to effectively improve the progress. Therefore, a slope concrete spraying device and a construction method thereof are proposed to solve the above problems. Summary of the Invention

Detailed implementation manners

[0017] Embodiment 1 As Figure 1-15As shown in the figure, a slope concrete spraying device includes a top slope moving mechanism 2 and a bottom slope moving mechanism 1 arranged on the top and bottom of the slope. A guiding mechanism 3 parallel to the slope is arranged between the top slope moving mechanism 2 and the bottom slope moving mechanism 1. The top slope moving mechanism 2, the bottom slope moving mechanism 1 and the guiding mechanism 3 form a "Z" shape adapted to the slope. A spraying mechanism 4 and a maintenance and film laying mechanism 5 that can slide along the height direction of the slope are arranged on the guiding mechanism 3. A lifting mechanism 6 that can be connected to the spraying mechanism 4 or the maintenance and film laying mechanism 5 is arranged on the top slope moving mechanism 2. A concrete spraying machine 7 is arranged on the bottom slope moving mechanism 1. The conveying end of the concrete spraying machine 7 is connected to the spraying mechanism 4 through a telescopic hose.

[0018] With such a design, the spraying mechanism 4 or the maintenance and film laying mechanism 5 can be lifted on the guiding mechanism 3 through the guiding mechanism 3, so as to realize the spraying work or the film covering work on the slope surface by using the parallel relationship between the guiding mechanism 3 and the slope surface. Furthermore, the spraying or film covering work at a short distance and with stability can be realized, ensuring the uniformity and thickness of the spraying, avoiding the waste of materials at the same time, reducing the labor intensity of construction workers, and greatly improving the work efficiency.

[0019] It should be noted that the concrete spraying machine 7 is a common commercially available product, so it will not be described in detail here.

[0020] In a preferred solution, the guiding mechanism 3 includes two connecting parts 301 respectively connected to the top slope moving mechanism 2 and the bottom slope moving mechanism 1. Two parallel guiding frames 302 are arranged between the two connecting parts 301. The guiding frame 302 includes a frame body 3020. In this embodiment, the frame body 3020 is a laterally inverted "U" shape, and the size of the frame body 3020 can be adjusted according to actual needs. An operation groove 3021 is arranged in the frame body 3020, which is convenient for the spraying mechanism 4 or the maintenance and film laying mechanism 5 to construct the slope surface. Slide bars 3022 are arranged on both sides of the operation groove 3021 on the frame body 3020.

[0021] In a preferred solution, the spraying mechanism 4 includes two symmetrically arranged first mounting plates 401. A first sliding sleeve shaft 402 that is slidably sleeved outside the slide bar 3022 is arranged at the front end of the first mounting plate 401. An installation frame 403 is arranged between the two first mounting plates 401. A spraying head 404 is arranged through the installation frame 403. The concrete spraying machine 7 is connected to the spraying head 404 through a telescopic hose. A first lifting ear 412 is arranged at the top of the first mounting plate 401, so that the lifting mechanism 6 can lift the spraying mechanism 4 by using the first lifting ear 412 to realize the vertical spraying on the slope surface. Cooperating with the movement of the device along the length direction of the slope, the spraying work of the entire slope surface can be realized.

[0022] It should be noted that the number of the spraying heads 404 and the concrete spraying machines 7 can be adjusted according to the spraying requirements.

[0023] In the preferred solution, rotary bearings 408 are provided on both of the two first mounting plates 401, and rotary shafts 409 installed in the rotary bearings 408 are provided at both ends of the mounting frame 403. The ends of the rotary shafts 409 pass through the rotary bearings 408, and push-pull rods 410 are arranged outside. A first telescopic cylinder 411 is hinged to the front side of the first sliding sleeve shaft 402. The telescopic end of the first telescopic cylinder 411 is hinged to the end of the push-pull rod 410. The first telescopic cylinder 411 can be an electric cylinder or a hydraulic cylinder.

[0024] With such a design, the mounting frame 403 can be rotated in the two first mounting plates 401 by the telescoping of the first telescopic cylinder 411, so as to adjust the spraying angle of the spraying head 404. When the slope surface is uneven, the spraying angle of the spraying head 404 can be adjusted to keep it perpendicular to the slope surface to a certain extent, realizing more refined spraying control and ensuring the uniformity and thickness of spraying.

[0025] Linking frames 405 are provided between the tops and bottoms of the two first mounting plates 401. The linking frames 405 can enhance the structural strength between the two first mounting plates 401. Laser ranging devices 406 and image acquisition devices 407 are provided on the separated sides of the two linking frames 405. Through repeated measurements between the upper and lower groups of laser ranging devices 406 and image acquisition devices 407, the thickness and angle of spraying can be controlled. For example, by measuring the distance from the slope surface with the laser ranging device 406 located below and calculating it with the preset distance after spraying, the actual thickness to be sprayed can be obtained, so as to adjust the spraying amount. At the same time, after spraying is completed, the laser ranging device 406 above can be used to measure the spraying thickness. When it is unqualified, secondary spraying can be carried out. Similarly, the image acquisition device 407 below can collect the flatness of the slope surface and adjust the spraying angle according to the flatness. After spraying is completed, the flatness after spraying can be collected by the image acquisition device 407 above. It should be noted that the number of the laser ranging devices 406 and image acquisition devices 407 can be adjusted according to the actual situation, and the laser ranging devices 406 and image acquisition devices 407 and their supporting controllers are all ordinary commercially available products.

[0026] In the preferred embodiment, the film maintenance and laying mechanism 5 includes two second mounting plates 501 and a film roll 505. The front end of the second mounting plate 501 is provided with a second sliding sleeve shaft 502 which is slidably mounted on the outside of the sliding rod 3022. The second mounting plate 501 is provided with a U-shaped groove 503 which is open upward. A receiving seat 504 is provided on the outer side of the bottom end of the U-shaped groove 503. The film roll 505 is rotatably placed on the receiving seats 504 of the two second mounting plates 501 through the reel at the center thereof. A limited position seat 506 is detachably installed on the receiving seat 504. A reeling and tensioning mechanism 507 is provided on the side of the two second sliding sleeve shafts 502 close to the slope. Second lifting ears 509 are provided on the tops of the two second mounting plates 501. The lifting mechanism 6 is connected to the film maintenance and laying mechanism 5 through the second lifting ears 509.

[0027] The receiving seat 504 and the limiting seat 506 are symmetrical semicircular. When the two are connected, a sleeve that is compatible with the reel of the film roll 505 is formed, and a plurality of balls are arranged on the inner side of both. The ends of the receiving seat 504 and the limiting seat 506 are provided with a docking plate 5041 extending outward, and a through hole 5042 is arranged on the docking plate 5041 of the receiving seat 504, and a screw 5061 that can pass through the through hole 5042 is arranged on the docking plate 5041 of the limiting seat 506, and a nut 5062 is installed after the screw 5061 passes through the through hole 5042.

[0028] With such a design, the film roll 505 can be disassembled, assembled and replaced through the cooperation of the receiving seat 504 and the limiting seat 506. At the same time, it can be unwound by rotating during the lowering process. The unwinding tensioning mechanism 507 can keep the film roll 505 in contact with the slope during the unwinding process.

[0029] A cutting mechanism 508 is also provided at the top of the two second sliding sleeve shafts 502, located between the film roll 505 and the unwinding tensioning mechanism 507, so as to facilitate cutting after the vertical laying is completed, so as to proceed to the next laying work.

[0030] Among them, the unwinding and tensioning mechanism 507 includes a spring telescopic rod 5070 respectively hinged on the two second sliding sleeve shafts 502, the spring telescopic rod 5070 is a common commercially available product, and a resistance rod 5071 is arranged between the telescopic ends of the two spring telescopic rods 5070. The two second sliding sleeve shafts 502 are also hinged with a second telescopic cylinder 5072, and the second telescopic cylinder 5072 is located below the spring telescopic rod 5070. The second telescopic cylinder 5072 can be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder, and the telescopic end of the second telescopic cylinder 5072 is hinged to the outer rod of the spring telescopic rod 5070.

[0031] With such a design, the resistance rod 5071 can tension the membrane under the action of the spring telescopic rod 5070, so that it maintains a distance from the slope surface. At the same time, when encountering protrusions, it can avoid them by telescoping. In addition, by telescoping the second telescopic cylinder 5072, the spring telescopic rod 5070 and the resistance rod 5071 can be rotated to adjust the tension, and they can be folded up when not in use to avoid unnecessary collisions.

[0032] The cutting mechanism 508 includes a first linear module 5080 arranged on the top of the two second sliding sleeve shafts 502. The first linear module 5080 is arranged in a vertical direction, and a third telescopic cylinder 5081 is vertically installed on its slide. The third telescopic cylinder 5081 can be a hydraulic cylinder, and a cutting machine 5082 is installed at the telescopic end of the third telescopic cylinder 5081.

[0033] With such a design, the operating height of the cutting machine 5082 can be adjusted by the third telescopic cylinder 5081. When not in use, it can be raised and cooperated with the lateral drive of the first linear module 5080 to achieve cutting of the film. At the same time, since the cutting mechanism 508 is arranged between the film roll 505 and the unwinding and tensioning mechanism 507, the film slope formed between the two facilitates cutting by the cutting mechanism 508.

[0034] In the preferred embodiment, the slope bottom moving mechanism 1 includes a bottom moving platform 101, and two groups of first rail wheel moving mechanisms 102 are symmetrically arranged at the bottom of the bottom moving platform 101. The first rail wheel moving mechanism 102 is a double-wheel structure, and one or both groups are driving wheel groups.

[0035] The slope top moving mechanism 2 includes a top moving platform 201, and two sets of second rail wheel moving mechanisms 204 are symmetrically arranged at the bottom of the top moving platform 201. The second rail wheel moving mechanism 204 is a single wheel structure or a double wheel structure, and one or both sets are driving wheel sets.

[0036] With such a design, the device can be moved on the track through the first track wheel moving mechanism 102 and the second track wheel moving mechanism 204. At the same time, the coordination between the track wheel and the track can achieve the effect of supporting the device. In addition, the first track wheel moving mechanism 102 and the second track wheel moving mechanism 204 are both common commercially available products.

[0037] A second linear module 203 is provided on the top of the top moving platform 201 for realizing the movement of the lifting mechanism 6 .

[0038] In this embodiment, a groove 202 is provided at the top of the top moving platform 201, and the second linear module 203 is built in the groove 202, reducing the use height of the hoisting mechanism 6. At the same time, both the first linear module 5080 and the second linear module 203 are screw linear modules, which are common prior arts, so no detailed description will be given here.

[0039] The hoisting mechanism 6 includes support columns 602 and a winch 601 that are arranged front and back on the sliding table of the second linear module 203. A pulley 603 is provided at the top of the support column 602. The steel wire rope on the winch 601 passes around the pulley 603 and is connected to the spraying mechanism 4 or the maintenance and film laying mechanism 5 through a hook. Thus, through the winding and unwinding of the winch 601, and in cooperation with the gravity of the spraying mechanism 4 or the maintenance and film laying mechanism 5, the lifting of the spraying mechanism 4 or the maintenance and film laying mechanism 5 can be realized.

[0040] Embodiment 2 Further described in combination with Embodiment 1, as Figure 1-16 shown in the structure, in order to facilitate the installation of the device on the slope, hinge seats 103 for connecting the guiding mechanism 3 are respectively provided at the opposite ends of the bottom moving platform 101 and the top moving platform 201. Two connecting parts 301 of the guiding mechanism 3 are respectively rotatably connected to the corresponding hinge seats 103 through rotating shafts 302. Thus, by rotating the guiding mechanism 3 and the top moving platform 201, it can be lapped on the slope.

[0041] In a preferred solution, a winding and unwinding mechanism 8 is provided on one side of the top of the bottom moving platform 101 away from the guiding mechanism 3. While adjusting the angle of the guiding mechanism 3, it also plays a counterweight role accordingly. It should be noted that counterweight blocks can also be provided on the bottom moving platform 101 to improve its counterweight effect.

[0042] The winding and unwinding mechanism 8 includes a support frame 801 provided on the top of the bottom moving platform 101. Two rotating shaft seats 802 are symmetrically provided at the top of the support frame 801. A transmission shaft 803 is rotatably arranged between the two rotating shaft seats 802. Both ends of the transmission shaft 803 pass through the rotating shaft seats 802 and are connected with winding drums 804. A support platform 805 is also provided outside the support frame 801. A driving device 806 is provided on the support platform 805. The driving device 806 is composed of a motor and a reducer. A transmission assembly 807 is provided between the output shaft of the driving device 806 and the transmission shaft 803. The transmission assembly 807 can be a synchronous belt and synchronous wheel structure, a chain and sprocket structure, or a gear meshing structure.

[0043] There are two third lifting lugs 303 symmetrically arranged on the connecting part 301 at the top. The steel wire ropes wound on the winding drum 804 are connected to the corresponding third lifting lugs 303. Thus, the angle adjustment of the guiding mechanism 3 can be realized by the winding and unwinding of the steel wire ropes by the winding drum 804. At the same time, when it is not in use, it can also be lifted to achieve the effects of quick removal and convenient transfer.

[0044] Angle adjustment mechanisms 9 are arranged between both sides of the slope top moving mechanism 2 and the guiding frame 302. The angle adjustment mechanism 9 includes a support rod 901 arranged outside the frame body 3020. A fourth telescopic cylinder 902 is hinged on the support rod 901. The fourth telescopic cylinder 902 is a hydraulic cylinder. Extension rods 903 are arranged on both sides of the top moving platform 201. The telescopic end of the fourth telescopic cylinder 902 is hinged to the end of the extension rod 903.

[0045] With such a design, the angle of the slope top moving mechanism 2 can be adjusted by the telescoping of the fourth telescopic cylinder 902. Thus, after adjusting the guiding mechanism 3 to a suitable angle, the slope top moving mechanism 2 can be seated on the track at the top of the slope by the fourth telescopic cylinder 902.

[0046] The wheel body of the second track wheel moving mechanism 204 includes a moving part 2040 that moves on the track. A support part 2041 that can abut against the side surface of the track is arranged on one side of the moving part close to the slope. With such a design, it is convenient for the second track wheel moving mechanism 204 to be seated on the track by rotation while not affecting the support effect of the device.

[0047] It should be noted that in order to avoid the situation of gravity imbalance and tipping due to excessive retraction of the guiding mechanism 3, the maximum retraction angle of the guiding mechanism 3 is less than ninety degrees, so that the guiding mechanism 3 and the slope top moving mechanism 2 can always maintain a forward inclination state.

[0048] Embodiment 3 Combined with Embodiments 1 and 2 for further illustration, as Figure 17-18 shown in the structure, according to the construction method of the slope concrete spraying device described above, the method includes: S1.
