Description

TECHNICAL FIELD

[0001] The application relates to the roadway tunneling supporting technology field, in particular to an anchor rod jumbo with a supporting function. BACKGROUND

[0002] With the development of industrial technology, the exploration of the human race to the underground is deepening, and in the process of tunneling, an anchor rod jumbo needs to be used to drill anchor rods into the roadway to reinforce the roadway. However, the process of advancing the anchor rod needs a certain period of time, and during this period, if the roadway collapses, it may affect the life safety of the construction personnel. Therefore, a supporting device needs to be used to support the roadway.

[0003] In order to further improve the portability of the supporting device, the supporting device is generally directly installed on the anchor rod jumbo. However, the anchor rod jumbo at the present stage usually only has one supporting arm, and the supporting point is relatively single, and cannot simultaneously support the top and side of the roadway. Therefore, an anchor rod jumbo with stronger supporting capacity is urgently needed. CONTENT OF THE INVENTION

[0004] One of the purposes of the application is to provide an anchor rod jumbo with a supporting function.

[0005] In order to achieve the above at least one purpose, the technical scheme adopted by the application is: an anchor rod jumbo with a supporting function, comprising a vehicle body, a first supporting arm is rotatably installed on the vehicle body, and a second supporting arm is rotatably connected to the first supporting arm; a first supporting assembly and a first telescopic oil cylinder for adjusting the angle of the first supporting arm are installed on the first supporting arm, the first supporting assembly comprises two telescopic rods with opposite telescopic directions, and a supporting rod is installed on the moving section of the telescopic rod; and a second supporting assembly is installed on the second supporting arm.

[0006] Through the above setting, the supporting angles of the first supporting arm and the second supporting arm can be adjusted, and the two supporting arms can support the top and side of the roadway according to the actual situation of the roadway, which can effectively improve the applicability of the device and the safety of the construction personnel. The second supporting arm is directly connected with the first supporting arm, which effectively reduces the occupied space and manufacturing cost of the second supporting arm. The first supporting assembly and the second supporting assembly can increase the supporting area of the two supporting arms to the roadway, and further improve the supporting stability of the device.

[0007] Preferably, the first support arm is telescopic, and a rotating section, a middle telescopic section and an inner telescopic section are sequentially arranged on the first support arm; the rotating section is rotationally connected with the vehicle body; the middle telescopic section and the inner telescopic section are used for adjusting the length of the first support arm; and the inner telescopic section is provided with a mounting portion at the end thereof, and the telescopic rod is mounted on the mounting portion. In this way, the limit height of the first support arm can be further improved, so that the device can adapt to a larger size roadway; in addition, the first support arm is arranged in a telescopic form, so that the occupied space of the first support arm can be further reduced; when the construction is stopped, the middle telescopic section and the inner telescopic section can be retracted into the rotating section, so that the overall occupied space of the first support arm is reduced.

[0008] Preferably, a first telescopic oil cylinder for adjusting the pitch of the first support arm is mounted between the rotating section and the middle telescopic section. In this way, the support angle of the first support arm can be controlled through the first telescopic oil cylinder.

[0009] Preferably, a top support is further mounted on the mounting portion, the top support is in a T shape, and an upper surface of the top support for matching the support of the roadway is an arc surface. In this way, when the top of the roadway is in an arch shape, the top support can be matched with the highest point of the roadway, and can support the top of the arch-shaped roadway together with the support rod, so that the contact area with the roadway is improved, and the roadway is prevented from collapsing due to uneven stress.

In this way, the length of the second support arm can be changed through the fixed section and the adjusting section, so that when the position of the anchor rod drilling vehicle is not easy to adjust, the length of the second support arm can be changed to ensure that the second support assembly can support the roadway.

[0011] Preferably, the adjusting mechanism is a limiting cooperation structure of a plug rod and a gear recess; a plurality of gear recesses are arranged on the adjusting section; and the plug rod is mounted on the fixed section and is used for limiting the extension length of the adjusting section in cooperation with the gear recess. In this way, when the position of the adjusting section is changed to a required point, the position of the adjusting section can be fixed by inserting the plug rod into the corresponding gear recess.

[0012] Preferably, the second support assembly comprises a plurality of mutually hinged support nets, and the end surface of a support net located at the center is hinged with the adjusting section. In this way, after the construction is completed, the support nets on both sides can be folded onto the support net located at the center, so that the occupied space of the second support assembly is further reduced.

[0013] Preferably, a second telescopic oil cylinder for adjusting the pitch of the second support arm is installed between the first support arm and the second support arm. In this way, the support angle of the second support arm can be controlled through the second telescopic oil cylinder.

[0014] Preferably, at least one anchor rod arm is installed on the vehicle body. In this way, when the first support arm and the second support arm are supporting, the anchor rod arm can be used to lay anchor rods in the roadway.

[0015] Preferably, the number of anchor rod arms is two, and the two anchor rod arms cooperate to form a channel for accommodating the first support arm and the second support arm. In this way, when the machine stops working, the first support arm and the second support arm can be accommodated in the channel to further reduce the overall size of the anchor rod drill carriage.

In addition, the first support arm and the second support arm both have telescopic function, and the occupied space of the two support arms can be reduced by contraction.

[0018] The support frame and the top support on the first support arm can cooperate with each other to support the top of the roadway more comprehensively, so as to avoid the collapse of the roadway; the support net on the second support arm can be folded, and after construction is completed, the support nets on both sides can be folded to the middle support net, thereby further reducing the occupied space of the protective net; the utility model has the advantages of strong support ability, strong applicability and small occupied space.

DETAILED DESCRIPTION

[0029] Hereinafter, the application will be further described in conjunction with specific embodiments, and it should be noted that, without conflict, the following described embodiments or technical features can be combined in any manner to form new embodiments.

[0030] In the description of the application, it should be noted that, for orientation words, such as the terms "center", "transverse", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. The orientation and positional relationship shown in the drawing is based on the orientation or positional relationship shown in the drawing, and is only for the convenience of describing the application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and cannot be understood as limiting the specific protection scope of the application.

[0031] It should be noted that the terms "first", "second" and the like in the specification and claims of the application are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence.

[0032] The terms "comprise" and "have" and any variations thereof in the specification and claims of this application are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or apparatus that comprises a list of steps or units is not necessarily limited to those steps or units that are clearly listed, but includes other steps or units that are not clearly listed or inherent to such processes, methods, products or apparatuses.

[0033] One aspect of the present application provides a support anchor drill rig, as shown in Figure 1 and Figure 2 , wherein a preferred embodiment comprises a vehicle body 3, a first support arm 1 rotatably mounted on the vehicle body 3, and a second support arm 2 rotatably connected to the first support arm 1. When the drill rig is working, the first support arm 1 and the second support arm 2 can be used to support the roadway, and the angle between the first support arm 1 and the second support arm 2 can be adjusted, so that the construction personnel can adjust the inclination angle of the first support arm 1 and the second support arm 2 according to the actual situation of the roadway, thereby providing more suitable support for the roadway.

[0034] Further, as shown in Figure 1 , Figure 3 and Figure 4 , in order to further improve the support effect of the first support arm 1 and the second support arm 2 on the roadway, a first support assembly 100 and a first telescopic oil cylinder 301 are mounted on the first support arm 1. The first support assembly 100 comprises two telescopic rods 101 with opposite telescopic directions, and a support rod 102 is mounted on a movable end of the telescopic rod 101, so as to provide a larger range of support for the top of the roadway. The first telescopic oil cylinder 301 can control the pitch angle of the first support arm 1 by itself, thereby further improving the applicability of the device. A second support assembly 200 is mounted on the second support arm 2 to support the side of the roadway.

[0035] It can be understood that the second support arm 2 in the present application is directly connected with the first support arm 1, which effectively reduces the occupied space and manufacturing cost of the second support arm 2. At the same time, the design of the double arms can support the top and side of the roadway respectively, effectively avoiding the probability of roadway collapse, thereby improving the safety protection of the construction personnel.

[0036] In some embodiments of the present application, in order to further improve the applicability of the device, as shown in Figure 5As shown, the first support arm 1 is telescopic, and the first support arm 1 is sequentially provided with a rotating section 11, a middle telescopic section 12 and an inner telescopic section 13; wherein the angle of the rotating section 11 is adjustable; the middle telescopic section 12 and the inner telescopic section 13 are used to adjust the length of the first support arm 1, so as to ensure that the first support arm 1 can be adjusted according to the actual tunnel condition. In order to install the first support assembly 100, an installation portion 14 is arranged at the end of the inner telescopic section 13, and the telescopic rod 101 is installed on the installation portion 14.

[0037] It can be understood that, by setting the first support arm 1 to be telescopic, the occupied space of the first support arm 1 can be further reduced; and the middle telescopic section 12 and the inner telescopic section 13 can be retracted into the rotating section 11 when the construction is stopped, so as to reduce the overall size of the first support arm 1.

[0038] In addition, in some other embodiments of the present application, an elastic member can be connected between the installation portion 14 and the inner telescopic section 13, and the elastic member can be used to automatically adjust the included angle between the support rod 102 and the tunnel, so as to ensure that the support rod 102 can be fitted with the tunnel.

[0039] Specifically, as shown in Figure 2 , one end of the first telescopic oil cylinder 301 is rotationally connected with the rotating section 11, and the other end is rotationally connected with the vehicle body 3; when the first telescopic oil cylinder 301 is adjusted, the rotating section 11 can be jacked up or pulled back with the vehicle body 3 as the support point.

[0040] In the present embodiment, as shown in Figure 4 and Figure 5 , the installation portion 14 is further provided with a top support 103, the top support 103 is in T shape, the lower end of the top support 103 is connected with the installation portion 14, and the upper end of the top support 103 is used to support the tunnel. Since the top of part of the tunnel is arched, in order to better fit the top support 103 with the top of the tunnel, the side of the top support 103 used to cooperate with the support rod 102 to support the tunnel is arranged to be arc-shaped, so as to improve the support effect on the top of the tunnel.

[0041] It should be noted that the top support 103 can cooperate with the support rod 102 to more comprehensively support the top of the tunnel, avoid uneven stress on the top of the tunnel, and effectively reduce the probability of tunnel collapse.

[0042] In the present embodiment, as shown in Figure 5As shown, the second support arm 2 is also telescopic, and a fixed section 21 and an adjusting section 22 are arranged on the second support arm 2, the adjusting section 22 is slidingly installed inside the fixed section 21, and the second support assembly 200 is installed on the adjusting section 22, so that the second support assembly 200 can move synchronously with the adjusting section 22, and when the second support arm 2 reaches a specified point, the second support assembly 200 can be made to act on the side of the roadway by moving the adjusting section 22. One end of the fixed section 21 is rotatably connected with the first support arm 1, for adjusting the angle of the second support arm 2. In addition, in order to realize the adjustable function of the second support arm, an adjusting mechanism is arranged on the fixed section 21 and the adjusting section 22.

[0043] Specifically, as shown in the Figure 6 adjusting mechanism is a limiting cooperation structure of the plug rod 210 and the gear recess 220, a plurality of gear recesses 220 are arranged on the adjusting section 22 along the length direction of the adjusting section 22, and the plug rod 210 is arranged on the fixed section, when the length of the second support arm 2 needs to be adjusted, the plug rod 210 can be taken out and the adjusting section 22 is moved to the required position, and then the plug rod 210 is inserted into the corresponding gear recess 220, so that the extension length of the adjusting section 22 can be limited, and the applicability of the device is further improved.

[0044] Further, as shown in the Figure 7 , Figure 8 and Figure 9 , the second support assembly 200 includes a plurality of support nets 201 hingedly connected with each other, and the end face of a support net 201 located at the center is hingedly connected with the adjusting section 22; when the roadway needs to be supported, the plurality of support nets 201 can be unfolded, so as to increase the area of the roadway supported, and further improve the supporting effect of the device; when the supporting is completed, the support nets 201 on both sides can be folded onto the support net 201 located at the center, so as to further reduce the occupied space of the second support assembly 200.

[0045] In this embodiment, as shown in the Figure 2 , a second telescopic oil cylinder 302 is installed between the first support arm 1 and the second support arm 2; the second telescopic oil cylinder 302 is used to adjust the pitch angle of the second support arm 2.

[0046] It can be understood that the second telescopic oil cylinder 302 can cooperate with the first telescopic oil cylinder 301 described above, and the support angles of the first support arm 1 and the second support arm 2 can be adjusted according to the actual situation during the operation of the anchor rod drill carriage, so as to provide a more conformable supporting surface for the roadway.

[0047] Further, at least one anchor rod arm 31 is installed on the vehicle body 3, and when the first support arm 1 and the second support arm 2 are supporting, the anchor rod arm 31 can be used to lay the anchor rod in the roadway, so that the supporting work and the anchor inserting work can be carried out at the same time, and the construction efficiency is further improved.

[0048] It should be known that, due to the large volume of the first support arm 1 and the second support arm 2, if the two support arms are not stored, it will affect the normal driving of the machine itself or surrounding vehicles when the anchor rod drilling vehicle is driving.

[0049] In view of the above, in some embodiments of the present application, as shown in Figure 7 and Figure 8 , the number of anchor rod arms 31 is two, and the two anchor rod arms 31 cooperate to form a channel 310. When the machine stops working, the first support arm 1 and the second support arm 2 can be stored in the channel 310, further reducing the overall size of the machine.

[0050] The above describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application. The scope of protection claimed by the present application is defined by the appended claims and their equivalents.
