Technical Field
[0001] The utility model relates to the technical field of wet spraying trolleys, in particular to a concrete wet spraying trolley. Background Art
[0002] The wet spraying trolley, also known as the wet spraying manipulator or large robotic arm wet spraying machine, is a large-scale intelligent wet spraying equipment that integrates walking, pumping and spraying functions. It uses the concrete mixed in the concrete mixing station and pumps the concrete to the nozzle through wireless remote control. It then uses high-pressure air to spray onto the sprayed surface to form a concrete support layer. The wet spraying trolley has the advantages of flexible transfer, fast spraying speed, high construction quality, high degree of mechanization, and large operating range. It is widely used in shotcrete support operations in tunnel engineering, water conservancy and hydropower, slope support, mining development and other fields.
[0003] The existing wet spraying trolley's mechanical arm and pumping structure are integrated into the transfer vehicle body. During operation, the device is stabilized by hydraulic legs before the wet spraying operation begins. This results in the transfer vehicle being restricted to the work site, making it impossible to use the transfer vehicle for other necessary transfer work or to transport more wet spraying equipment. Therefore, we propose a concrete wet spraying trolley. Utility Model Content
[0004] The purpose of the utility model is to provide a concrete wet spraying trolley, which supports the base of the wet spraying device in a detachable manner and is placed on the carriage of a transfer vehicle. When the transfer vehicle transfers the device to a position where wet spraying is required, the hydraulic support legs can directly support the base and the structure above it to a position higher than the carriage. The wet spraying device located above the base can operate independently, and the transfer vehicle can be driven away to transport other wet spraying devices or tools, etc., thereby solving the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete wet spraying trolley, comprising a transfer trolley and a base, the base being placed on the surface of the carriage of the transfer trolley, a mechanical arm, a concrete pump and a control box being arranged above the base, a support groove being provided on the surface of the carriage of the transfer trolley, and the base being supported in the support groove of the carriage of the transfer trolley in a detachable manner; side panels are laterally fixed on both sides of the base, the side panels extend to the outside of the carriage of the transfer trolley, hydraulic support feet are vertically installed above both sides of the two side panels, and the protruding ends of the hydraulic support feet are passed through and placed under the side panels.
[0006] By adopting the above technical solution, the base and the wet spraying device above it can be placed on the carriage of the transfer vehicle and work. In order to facilitate the transfer vehicle to perform other transfer tasks, the lock between the base and the transfer vehicle carriage can be released, and the base and the structure above it can be supported and work alone, and the transfer vehicle can then perform other transfer tasks.
[0007] Optionally, auxiliary wheels are installed at the bottom of the side panels at the inner side of the hydraulic support feet, and the height of the auxiliary wheels is less than the height of the carriage of the transfer vehicle.
[0008] By adopting the above technical solution, when the base is supported alone and the wet spraying device is used, the auxiliary wheels can be used to achieve a small range of movement of the device.
[0009] Optionally, a handle is welded and fixed to the surface of the side panel, and the handle is located in the middle of the surface of the side panel.
[0010] By adopting the above technical solution, when the position of the device needs to be moved within a small range, a thrust can be applied to the side panels and the base through the handle.
[0011] Optionally, a support plate is fixed to the lower end of the hydraulic support foot, and the area of the support plate is larger than the bottom area of the hydraulic support foot.
[0012] By adopting the above technical solution, it is ensured that the hydraulic support legs can obtain a larger supporting area when supported on the ground.
[0013] Optionally, screw holes are provided at the four corners of the surface of the support groove, and locking bolts with their ends screwed into the screw holes are passed through the four corners of the base.
[0014] By adopting the above technical solution, when the transfer device of the transfer vehicle is moved, the base can be stably locked on the surface of the vehicle body by using the locking bolt.
[0015] Optionally, the bottom area of the branch groove is smaller than the area above the branch groove, and a guide groove is formed between the bottom of the branch groove and the upper opening.
[0016] By adopting the above technical solution, the base can be guided to the center when it is slowly placed in the support groove again.
[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0018] 1. The technical solution of the present application is to support the base of the wet spraying device in a detachable manner and place it on the carriage of a transfer vehicle. When the transfer vehicle transports the device to the location where wet spraying is required, the hydraulic support legs can directly support the base and the structure above it to a position higher than the carriage. The wet spraying device located above the base can operate independently, and the transfer vehicle can be driven away to transport other wet spraying devices or tools.
[0019] 2. The technical solution of the present application is to install auxiliary wheels under the side panels on both sides. When the wet spraying device on the base and above it works alone, in order to move the position of the wet spraying device in a small range, the hydraulic support legs can be lowered and the auxiliary wheels can be used to drive the device to move its position.

[0024] See also Figure 1-2 The utility model provides a technical solution: a concrete wet spraying trolley, which is similar to the existing technology in that it includes a transfer vehicle 1 and a base 2, the base 2 is placed on the carriage surface of the transfer vehicle 1, and a mechanical arm 21, a concrete pump 22 and a control box 23 are arranged above the base 2, wherein a nozzle is also installed at the end of the mechanical arm 21, the mechanical arm 21 is used to drive the nozzle to move to the position where wet spraying is required, and the output pipe of the concrete pump 22 is connected to the nozzle, the concrete pump 22 is used to deliver the concrete to the nozzle for spraying, and the control box 23 is used to achieve the purpose of controlling the mechanical arm 21 and the concrete pump 22. The above components are existing well-known technologies. In order to avoid being verbose, their specific structures and principles will not be further described.
[0025] In order to achieve the purpose of enabling the base 2 and the wet spraying structure above it to work independently, a support groove 11 is provided on the surface of the transfer vehicle 1, and the base 2 is supported in the support groove 11 of the transfer vehicle 1 in a detachable manner. Screw holes 112 are also provided at the four corners of the surface of the support groove 11, and locking bolts 24 with the ends screwed into the screw holes 112 pass through the four corners of the base 2. When the transfer vehicle 1 drives the base 2 and the structure above it for transportation, the base 2 and the structure above it can be locked to prevent them from falling from the vehicle compartment of the transfer vehicle 1.
[0026] The jacks 31 are fixed to the upper and lower ends of the base 2, and the jacks 31 are fixed to the lower ends of the base 2. The jacks 31 are fixed to the lower ends of the base 2, and the jacks 31 are fixed to the lower ends of the base 2. The area of the jacks 31 is larger than the area of the bottom of the hydraulic feet 31. When in use, the locking bolts 24 at the four corners can be unscrewed to release the lock between the base 2 and the base of the transfer vehicle 1. Then, the hydraulic feet 31 are started to extend downward and supported on the ground by the support plates 311. The extension is continued so that the base 2 is supported at the moving height above the transfer vehicle 1. After that, the transfer vehicle 1 can be driven away for transporting other equipment or tools. At this time, the wet spraying device on the base 2 can be used separately.
[0027] An auxiliary wheel 32 is installed at the bottom of the side panel 3 on the inner side of the hydraulic support foot 31. The height of the auxiliary wheel 32 is less than the height of the carriage of the transfer vehicle 1. When the transfer vehicle 1 drives the base 2 to move, the auxiliary wheel 32 will not touch the ground. When the wet spraying structure above the base 2 is used alone and the position of the wet spraying device needs to be moved in a small range, the hydraulic support foot 31 can be lowered to support the auxiliary wheel 32 on the ground and drive the device to move. A handle 33 is welded and fixed on the surface of the side panel 3. The handle 33 is located in the middle of the surface of the side panel 3. The handle 33 can be used to push the device so that it is driven by the auxiliary wheel 32 to move.
[0028] The bottom area of the support groove 11 is smaller than the area above it, and a guide groove 111 is formed between the bottom of the support groove 11 and the upper opening. When the base 2 needs to be supported and placed in the support groove 11 again, the hydraulic support foot 31 slowly lowers the base 2, which can be guided by the guide groove 111 so that the base 2 is centered in the support groove 11, and then the base 2 is locked in the support groove 11 of the transfer vehicle 1 compartment again by the locking bolt 24.
[0029] When in use, the base 2 and the overall structure above it are transported to the site where wet spraying construction is required by the transfer vehicle 1, the control box 23 of the equipment is energized, the hydraulic support feet 31 are started first to extend downward and are placed on the ground through the support plates 311, and the wheel supports of the transfer vehicle 1 are prevented from being raised, which can stabilize the base 2. In order to improve the stability of the support, a pad can be placed at the bottom of the hydraulic support feet 31 in advance, and then the feed pipe of the concrete pump 22 can be connected to the concrete delivery pipe, and the mechanical arm 21 is started to drive the spray head to the position where spraying is required to carry out the wet spraying of concrete; in order to facilitate the use of the transfer vehicle 1 to transport other wet spraying devices or other materials and tools, the transfer vehicle 1 can be used to transport the base 2 and the overall structure above it to the site where wet spraying construction is required, and then the hydraulic support feet 31 are started first, and then the hydraulic support feet 31 are tightened. The locking bolts 24 at the four corners are unlocked to release the lock between the base 2 and the transfer vehicle 1. Then, the control box 23 of the equipment is energized in the same way, the hydraulic support feet 31 are started to extend downward and supported on the ground by the support plates 311, and continue to extend so that the base 2 is supported at the moving height above the transfer vehicle 1. After that, the transfer vehicle 1 can be driven away to transport other equipment or tools. At this time, the same method as above can be used for wet spraying of concrete. In order to move the device position in a small range without the help of the transfer vehicle 1, the hydraulic support feet 31 can be retracted first to support the auxiliary wheels 32 on the ground. Then, the base 2 can be moved to the required position in a small range by the handle 33, and then the hydraulic support feet 31 are used again to cooperate with the support plates 311 to support the base 2, and then the wet spraying of concrete can be carried out. When the device needs to be removed after the work is completed, first ensure that the hydraulic support feet 31 support the base 2 to a position higher than the height of the car body, then slowly drive the transfer vehicle 1 to the position where the car body is placed under the base 2, and align the base 2 with the support groove 11 as much as possible, then slowly control the retraction length of the hydraulic support feet 31, so that the base 2 is slowly aligned and supported in the support groove 11 under the guidance of the guide groove 111 and placed above the car body of the transfer vehicle 1, and then use the locking bolts 24 to pass through the four corners of the base 2 and screw them into the screw holes 112, and then lock the base 2 and the structure above it above the transfer vehicle 1 again so that it can be transported.
