[0012] The utility model will be described below in combination with the accompanying drawings Figure 1 The utility model is described in detail, and the technical scheme in the utility model embodiment is clearly and completely described. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all. Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model.

[0013] The utility model provides a kind of rock drilling equipment trolley for tunnel construction, as shown in Figure 1 It can be implemented as follows: including trolley body 1, the trolley body 1 has multiple groups of rock drilling machine arms and walking mechanism;Protection device is installed on the trolley body 1.The protection device includes stand column 2 and main protection plate 3;The lower end of stand column 2 is fixed on trolley body 1, the upper end of stand column 2 is fixed with main protection plate 3, for supporting main protection plate 3, support height exceeds the control position of rock drilling trolley.

[0014] The rock drilling rig of the tunnel construction in the heterogeneous rock stratum in the application is characterized in that: the upper end surface of the main protection plate 3 is provided with two groups of auxiliary protection units corresponding to the front and rear surfaces of the upper end surface of the main protection plate 3, each group of auxiliary protection units is composed of an auxiliary protection plate 4 and a pushing cylinder 5, the pushing cylinder 5 is fixed on the upper end surface of the main protection plate 3, the telescopic end of the pushing cylinder 5 is connected with the auxiliary protection plate 4, and the pushing cylinder 5 is used for driving the auxiliary protection plate 4 to extend or retract, and the auxiliary protection plate 4 can extend the protection area of the upper part of the rig when the auxiliary protection plate 4 is extended by the corresponding pushing cylinder 5.

[0015] The rock drilling rig of the tunnel construction in the heterogeneous rock stratum in the application is characterized in that: the column 2 is a liftable structure.

[0016] The rock drilling rig of the tunnel construction in the heterogeneous rock stratum in the application is characterized in that: the rock drilling machine arm includes a first rock drilling machine arm 6, a second rock drilling machine arm 7 and a third rock drilling machine arm 8 corresponding to the lower end, the middle end and the upper end of the tunnel, and each group of rock drilling machine arms is of a telescopic length structure.

[0017] In the specific implementation of the rock drilling rig, the first rock drilling machine arm 6, the second rock drilling machine arm 7 and the third rock drilling machine arm 8 can be used for corresponding operation on the lower end, the middle end and the upper end of the tunnel, a protection device is installed on the rig body 1, the protection device can be adjusted in height by the column 2, the support height of the protection device is greater than the control position of the rock drilling rig, the main protection plate 3 and the auxiliary protection plate 4 on the front and rear surfaces of the protection device can be used for safety protection above the rock drilling rig during construction.

[0018] The following is the beneficial effect of the rock drilling rig in the tunnel construction:

[0019] I. Enhance the safety of the operator:

[0020] The protection device effectively protects the operator at the control position of the rock drilling rig. The main protection plate supported by the column can block the flying stones, dust and other foreign matters in the rock drilling area, so as to avoid direct harm to the operator and greatly reduce the safety risk in the construction process.

[0021] The liftable column further improves the flexibility and effectiveness of the protection. In different tunnel construction scenes, when the height of the tunnel changes greatly, the height of the column can be adjusted to make the main protection plate always in a suitable protection position, so that the operator can be reliably protected in different working conditions.

[0022] II. Improve the adaptability of the protection area:

[0023] The auxiliary protection unit on the upper end of the main protection plate significantly expands the protection range. When the auxiliary protection plate extends under the action of the push cylinder, it can extend the protection area of the upper part of the trolley, effectively dealing with the situation of multi-angle and large-range foreign matter splashing that may occur during rock drilling operation. Whether the potential danger comes from different directions such as the top and side of the tunnel, better protection can be provided, making the protection more comprehensive.

[0024] The retractable design of the auxiliary protection plate avoids interference with the normal operation of the trolley and other construction operations when additional protection areas are not needed, improving the convenience and flexibility of equipment use.

[0025] III. Improve the efficiency and accuracy of rock drilling operation:

[0026] The rock drill arms correspond to the lower, middle and upper ends of the tunnel respectively and are of telescopic structure. This design enables the rock drilling trolley to adapt to tunnels of different heights and shapes. During tunnel construction, the length and position of each rock drill arm can be adjusted flexibly according to actual needs, achieving precise rock drilling operation on different parts of the tunnel, reducing the operation adjustment time caused by equipment limitations, and thus improving the overall rock drilling efficiency.

[0027] The arrangement of multiple rock drill arms can simultaneously perform rock drilling operation on multiple parts of the tunnel. Compared with traditional single-arm or a small number of arm rock drilling equipment, the time of a single operation cycle is greatly shortened, further improving the construction progress and efficiency, which is conducive to the rapid advancement of tunnel engineering.

[0028] IV. Improve the versatility and adaptability of the equipment:

[0029] The adjustability of the protection device and the rock drill arm enables the rock drilling equipment trolley to be applicable to various tunnel construction environments. Whether it is a small, medium or large tunnel, whether it is a regular or irregular tunnel cross-section, the trolley can meet the construction requirements by adjusting the parameters of the protection device and the rock drill arm, reducing the cost and time of replacing different models of equipment due to differences in tunnels.

[0030] The overall structure of the trolley is reasonably designed, ensuring protection and rock drilling functions while having good mobility and stability. The running mechanism enables it to move and position smoothly in the tunnel, facilitating quick conversion between different construction areas, improving the overall versatility and adaptability of the equipment, and reducing the limitations on construction site conditions.

[0031] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
