Description

TECHNICAL FIELD

[0001] The present application relates to the field of concrete wet spraying machine technology, in particular to a cab and a wet spraying machine. BACKGROUND

[0002] The concrete wet spraying machine is often used for spraying protection after the excavation of underground mines and engineering tunnels. The model of the wet spraying machine is usually defined by the cubic capacity of the pumping device provided for conveying concrete per hour. For example, the UPS-30 type wet spraying machine, whose code means that the conveying capacity per hour is 30m 3 The wet concrete spraying machine (hereinafter referred to as the wet spraying machine) is often used in tunnel engineering.

[0003] For the cab of the wet spraying machine, such as the UPS-30 type wet spraying machine described above, the functional areas of the cab can be reasonably arranged in the cab according to the guidance of GB / T21938 “Comfortable area and reachability range of earth-moving machinery operation”. For underground metal mines, the wet spraying machine of the UPS-20 type and the UPS-18 type and below is often used, which is convenient for the wet spraying machine to shuttle in the underground tunnel and to turn in the underground tunnel through the minimum turning radius designed for the wet spraying machine. For the wet spraying machine of the UPS-20 type and the UPS-18 type and below, the overall design height is ≤1800mm, and the overall design width is in the range of 1600-1800mm. Therefore, for the design of the cab, it means that the size of the cab is compressed with the reduction of the overall size of the machine, which makes it difficult to divide the functional areas in the cab.

[0004] Since the arrangement of various functional devices of the machine is close to the cab, the potential operation hazards should be considered before the design of the cab. The boundary sense of the driving area should be satisfied through reasonable structure. The devices that intersect with the cab should be excluded from the driving area as much as possible to improve the boundary sense and achieve safe driving.

[0005] The Chinese patent application with the application number 202410710094.5 discloses a concrete wet spraying vehicle. The cab assembly is arranged on the rear frame of the vehicle tail close to the pumping device and is horizontally arranged on one side of the hinged part between the vehicle head and the vehicle tail. The cab can be used for the driver to ride and drive the vehicle. By horizontally arranging the cab at the vehicle tail, the length of the cab can be effectively reduced, so that the width direction of the vehicle tail at the position of the cab can be fully utilized, thereby making the arrangement of the vehicle tail more compact and effectively reducing the volume of the vehicle tail. By arranging the cab at the vehicle tail, the steering difficulty of the vehicle head due to excessive weight can be avoided.

[0006] The vehicle frame further comprises an operation panel fixed to one side of the vehicle head close to the vehicle tail, and the side of the cab assembly close to the operation panel is provided with an operation opening.

[0007] The technical concept of the application is to set the cab at the vehicle tail and fix the operation panel to one side of the vehicle head close to the vehicle tail, and to realize driving control of the wet spraying machine through the operation opening of the cab assembly close to the operation panel.

[0008] Although the technical concept of the application can reduce the length of the cab and make the overall structure compact, the comfort of the control area is difficult to guarantee because the control part is separated from the cab, and the time lag of the driver's operation and command is inevitable because the arm has to pass through the operation opening. In addition, the vehicle head and the vehicle tail of the application are also hinge-connected in the middle, so the driving panel arranged at the vehicle head and the cab arranged at the vehicle tail swing with the vehicle head and the vehicle tail, which makes the driver unable to obtain a sense of security and prone to driving fatigue.

[0009] In addition, the passage device and the minimum entrance size are also important components affecting driving, and no technical disclosure is found. SUMMARY
