DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0021] In the present invention, terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate directions and positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and should not be understood as limiting the specific scope of protection of the present application.

[0022] Tunnel equipment transportation device, such as Figure 2 , Figure 3 and Figure 4 As shown, it includes two pairs of portal frames, each pair of portal frames includes two columns 1, a crossbeam 2 and a walking wheel 3 at the bottom of the column 1, and a door opening 4 is formed by the columns 1 and the crossbeam 2; the two pairs of portal frames are arranged front and back in the longitudinal direction, and the front and rear portal frames are connected into a whole through the longitudinal connecting rods 5 located on both sides, and the door openings 4 of the front and rear portal frames are connected to form a passage. In order to ensure the overall stability of the frame surrounded by the front and rear portal frames, preferably, a diagonal brace 10 is also provided between the columns 1 of the front portal frame and the columns 1 of the rear portal frame. The passage formed by the door openings 4 of the front and rear portal frames is used for the passage of the mineral material transfer belt, that is, when in use, the portal frame straddles the mineral material transfer belt and does not affect the operation of the mineral material transfer belt. Since the portal frame straddles the mineral material transfer belt, only the columns 1 on both sides of the mineral material transfer belt are supported on the ground. Compared with the overall station of the device on one side of the mineral material transfer belt, the space above the mineral material transfer belt is reasonably utilized, the floor area is greatly reduced, and the influence of the tunnel size is small. Furthermore, the upright column 1, the cross beam 2 and the longitudinal connecting rod 5 form a frame structure with good supporting performance. The arrangement of the traveling wheel 3 enables the traveling trolley of the tunnel equipment transport device type to travel as required.

[0023] A lower bracket is formed into a square by a crossbeam 2 and a longitudinal connecting rod 5, and an upper bracket 7 is arranged above the lower bracket; the upper bracket 7 is supported on the lower bracket along the vertical movement through a jacking mechanism 6, that is, under the drive of the jacking mechanism 6, the upper bracket 7 can adjust its installation height vertically, so that under the action of the walking wheel 3, the tunnel equipment transportation device moves longitudinally along the mineral material transfer belt to below the designated installation position of the funnel, and the upper bracket 7 can lift the funnel, and under the action of the jacking mechanism 6, the funnel is jacked to the designated installation position on the top of the box gallery for installation.

[0024] In order to guide the movement of the upper bracket 7 and prevent the upper bracket 7 from deviating, a guiding mechanism for guiding and limiting the movement of the upper bracket 7 is provided.

[0025] The guide mechanism can be a slide rail and a slide groove, etc. In this embodiment, the cross beam 2 is vertically arranged in the middle of the column 1, and the column 1 vertically includes an upper segment 1A located above the cross beam 2 and a lower segment 1B located below the cross beam 2; the upper bracket 7 is a square frame; the cross section of the upper segment 1A is right-angled, and its right-angle opening faces inward; the four corners of the upper bracket 7 are vertically slidably matched with the right-angle opening of the upper segment 1A, and the guide mechanism is formed by the right-angle opening of the upper segment 1A and the corner of the upper bracket 7. The upper bracket 7 is limited and guided by the corner structure of the upper segment 1A of the column 1, and there is no need to perform additional processing on the column 1, which saves processing steps; at the same time, the column 1 is an integral body, and the strength is guaranteed; the guide mechanism is formed by the corresponding structures of the column 1 itself and the upper bracket 7 itself, and the structure is simpler.

[0026] The lifting mechanism 6 may be a scissor mechanism, a rack and pinion mechanism, etc. In the present embodiment, the lifting mechanism 6 is a hydraulic cylinder.

[0027] Equipment such as funnels can be placed directly on the upper bracket 7, can be bound to the upper bracket 7, or can be fixed to the upper bracket 7 with bolts, etc. Of course, equipment placement grooves 8 may also be provided in the middle of the four sides of the upper bracket 7, and support legs may be provided at the bottom of equipment such as funnels, which are inserted into the equipment placement grooves 8 for lifting.

[0028] In order to transport components such as pipes and plates, preferably, component placement grooves 9 extending in the longitudinal direction are respectively provided on both sides of the portal frame in the transverse direction, and one end of the component placement groove 9 is fixed to the column 1 of the portal frame on the front side, and the other end is fixed to the column 1 of the portal frame on the rear side. Components such as pipes and plates are placed in the component placement grooves 9 on both sides for transportation.

[0029] In order to further improve the stability of transportation, preferably, the component placement groove 9 is vertically arranged at the bottom of the column 1. Compared with being arranged in the middle or top of the column 1, the component placement groove 9 arranged at the bottom of the column 1 is firstly convenient for placing the component into the component placement groove 9, and secondly, when the component is placed, the center of gravity of the entire transport device is lowered, and the stability is better.

[0030] The following uses the funnel as an example of the equipment to be transported and installed to explain the use of the tunnel equipment transportation device:

[0031] First, place the funnel on the upper support 7 outside the tunnel and fix it;

[0032] Next, the tunnel equipment transport device is driven by traction or driving wheels to straddle both sides of the transport belt and drive into the tunnel along the extension direction of the ore transport belt until the funnel reaches below the installation position; pipes, plates and other components can be placed in the component placement slot 9 at the same time and transported together with the funnel;

[0033] Then, the column 1 is used as a constraint, and the hydraulic cylinder synchronously lifts the upper bracket 7 to ensure that the funnel is lifted to the installation position stably and safely for installation.

[0034] The "tunnel" mentioned in the present invention can be a tunnel, a box gallery, a pipe gallery, etc.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
