[0049] A trolley for tunnel primary support construction relates to the field of tunnel construction equipment, and is mainly used to solve the problems of single function and long time of entering and leaving the scene in the prior art. The composition structure and working principle of the trolley for tunnel primary support construction are described below.
[0050] Referring to the accompanying Figure 1 and the accompanying Figure 2 The trolley for tunnel primary support construction mainly comprises a vehicle body 10, an arch lifting device 20, an upright arch device, a wet spraying mechanical arm 50 and a drilling mechanical arm 60.
[0051] The vehicle body 10 has a tracked chassis 11, and the tracked chassis 11 has strong adaptability and can travel on an uphill and a downhill. A plurality of slide rails 13 and driving devices are arranged longitudinally on the vehicle body 10, and the upright arch device, the wet spraying mechanical arm 50 and the drilling mechanical arm 60 can move forward and backward along the slide rails 13.
[0052] The arch lifting device 20 is arranged at the rear end of the vehicle body 10 (the end of the vehicle body 10 facing the working face is the front end), and is used to lift the arch 70. In the embodiment, the arch 70 is a folding arch, and the folding arch is formed by hinging a middle section and two side sections. The arch lifting device 20 is used to lift and unfold the folding arch, so as to facilitate a worker to connect the folding arch into a complete rigid arch by using bolts. The arch lifting device has the following two implementation modes.
[0053] Referring to the accompanying Figure 3One of the arch lifting devices comprises a second rotating arm 24, the rotating end of which is arranged on the column 12 of the vehicle body, and a third rotating arm 25, the rotating end of which is arranged on the free end of the second rotating arm 24, and a second toggle arm 26 is arranged on the free end of the third rotating arm 25, and the second toggle arm 26 is rotatably hinged on the free end of the second rotating arm 24. The second rotating arm 24 and the third rotating arm 25 are driven to rotate by a hydraulic rotary disc, and the length of the third rotating arm 25 is greater than the length of the second rotating arm 24.
[0054] Referring to the drawings Figure 4-8 Before lifting, the three pieces of folded arch are placed on the second toggle arm 26 by using a forklift, and then the folded arch is lifted upward by the cooperation of the second rotating arm 24 and the third rotating arm 25. When the folded arch is lifted to a specified height, the mechanical claw 39 on the main arch mechanical arm 30 grabs the middle section of the folded arch, and then the side sections of the folded arch are rotated outward by the cooperation of the second rotating arm 24 and the third rotating arm 25 until the folded arch is completely unfolded. Finally, the side sections and the middle section of the arch are connected by using bolts to form a complete arch 70.
[0055] Referring to the drawings Figure 9 Another arch lifting device comprises a sliding table 21 and a first rotating arm 22, the sliding table 21 is driven to move up and down along the column 12 of the vehicle body 10. The rotating end of the first rotating arm 22 is arranged on the sliding table 21, and is driven to rotate by a hydraulic rotary disc, and a first toggle arm 23 for forking the folded arch is arranged on the free end of the first rotating arm 22, and the first toggle arm 23 is rotatably hinged on the free end of the second rotating arm 24.
[0056] Compared with the former arch lifting device, the sliding table 21 can move up and down along the column 12, which is equivalent to the rotation of the first rotating arm 22, so the latter arch lifting device can also lift the folded arch and unfold the folded arch.
[0057] The arch erecting device is composed of a main arch mechanical arm 30 and two auxiliary arch mechanical arms 40, and its main function is to replace the arch erecting trolley to realize the hoisting of the arch 70. In this embodiment, the main arch mechanical arm 30 is arranged on the top of the vehicle body 10 in the longitudinal direction, and the two auxiliary arch mechanical arms 40 are arranged on the two sides of the vehicle body 10 in the longitudinal direction.
[0058] Referring to the drawings Figure 10 and the drawings Figure 11 The main arch mechanical arm 30 is mainly composed of a sliding seat 31, a turnover part 32, an extension arm 33, a first connecting rod 34, a second connecting rod 35, a first oil cylinder 36, a second oil cylinder 37, a third oil cylinder 38 and a mechanical claw 39, wherein the sliding seat 31 can move forward and backward along the sliding rail 13. The main arch mechanical arm 30 has a turnover structure with degrees of freedom, and its function is to move the arch 70 into the working face by longitudinal turnover in a limited space.
[0059] Specifically, the turnover member 32 is arranged below the telescopic arm 33, one end of the turnover member 32 is hinged to the sliding base 31, thereby forming a first rotating mechanism, the first rotating mechanism is driven by the first oil cylinder 36, and is used to realize rotation of the turnover member 32. The other end of the turnover member 32 is hinged to the telescopic arm 33, the first connecting rod 34 and the second connecting rod 35, thereby forming a second rotating mechanism, the second rotating mechanism is a four-bar linkage mechanism, is driven by the second oil cylinder 37, and is used to realize rotation of the telescopic arm 33.
[0060] In the embodiment, the telescopic arm 33 is a three-section hydraulic telescopic arm 33. The third oil cylinder 38, the third connecting rod 391 and the mechanical claw 39 are hinged to the telescopic end of the telescopic arm 33, thereby forming a third rotating mechanism for realizing up-down rotation of the mechanical claw 39.
[0061] Referring to the drawings Figure 12 The mechanical claw 39 mainly comprises a base 392, a hydraulic rotary motor 393, a support 394, a rocker arm 395, a fourth oil cylinder 396 and hydraulic clamps 397. The base 392 is hinged to the telescopic end of the telescopic arm 33, the hydraulic rotary motor 393 is installed between the base 392 and the support 394, and is used to drive the support 394 to rotate horizontally. The fourth oil cylinder 396 is hinged between the support 394 and the rocker arm 395, and is used to drive the rocker arm 395 to swing laterally. The hydraulic clamps 397 are two, and are arranged at two ends of the rocker arm 395 respectively, and are used to clamp the arch 70.
[0062] Referring to the drawings Figure 13 The auxiliary arch erecting mechanical arm 40 also has a telescopic turnover structure and a mechanical claw 39 for grabbing the arch 70. Since the space is relatively abundant, the auxiliary arch erecting mechanical arm 40 can directly turn over the arch 70 into the working face. In addition, the auxiliary arch erecting mechanical arm 40 has a basket 41 for carrying workers to work at height, and the basket 41 has an independently adjustable movement mechanism. When working, the auxiliary arch erecting mechanical arm 40 can lift the workers to any position. Therefore, in addition to assisting the main arch erecting mechanical arm 30 to install the arch 70, the auxiliary arch erecting mechanical arm 40 can also replace the charging trolley to install explosives in the excavation hole.
[0063] In the prior art, the arch erecting mechanical arm located at the top of the trolley has a limited distance from the arch top, and it is difficult to realize turnover and turning. The main arch erecting mechanical arm 30 can realize turnover and turning.
[0064] Referring to the drawings Figure 14-18Firstly, the main arch mechanical arm 30 and two pairs of secondary arch mechanical arms 40 (not shown in the figure) are moved to the rear end of the trolley, the mechanical claws 39 grab the three sets of arches 70 lifted by the arch lifting device 20, and then the arches 70 are moved to the rear end of the trolley. Through the cooperation of the first rotating mechanism, the second rotating mechanism, the third rotating mechanism, and the telescopic arm 33, the telescopic arm 33 can realize turning around in a limited space. After turning around, the arches 70 enter the tunnel face through the cooperation of the first rotating mechanism, the second rotating mechanism, the third rotating mechanism, and the telescopic arm 33, and the position of the arches 70 is adjusted in the longitudinal and height directions. Since the mechanical claws 39 have three-direction adjustment freedom, the installation position of the arches 70 can be accurately adjusted in a small range.
[0065] Referring to the accompanying drawings Figure 19 The wet spraying mechanical arm 50 is longitudinally arranged below the main arch mechanical arm 30, and has nine degrees of freedom, which can replace the wet spraying trolley to spray concrete to the tunnel arch face. The wet spraying mechanical arm 50 mainly comprises a telescopic large arm 51, a large arm angle adjusting oil cylinder 52, a first hydraulic rotary disc 53, a telescopic small arm 54, a small arm angle adjusting oil cylinder 55, a second hydraulic rotary disc 56, a turnover mechanism 57, and a nozzle 58. The large arm angle adjusting oil cylinder 52 is hinged between the sliding seat 31 and the telescopic large arm 51, and is used for adjusting the rotation angle of the telescopic large arm 51 in the horizontal plane. The first hydraulic rotary disc 53 is coaxially installed at the telescopic end of the telescopic large arm 51, the telescopic small arm 54 is hinged at the rotating end of the first hydraulic rotary disc 53, the small arm angle adjusting oil cylinder 55 is hinged between the first hydraulic rotary disc 53 and the telescopic small arm 54, and is used for adjusting the rotation angle of the telescopic small arm 54. The second hydraulic rotary disc 56 is vertically installed at the telescopic end of the telescopic small arm 54, the turnover mechanism 57 is installed at the rotating end of the second hydraulic rotary disc 56, the turnover mechanism 57 has an eccentric inclined rotating turnover frame 575. The nozzle 58 is installed on the turnover frame 575, and is used for spraying concrete.
[0066] Referring to the accompanying drawings Figure 20The overturning mechanism 57 mainly comprises a frame body 571, a hydraulic motor 572, an eccentric disc 573, a universal joint 574 and an overturning frame 575. The frame body 571 is installed at the rotating end of the second hydraulic rotary disc 56. The hydraulic motor 572 and the universal joint 574 are installed on the frame body 571. The eccentric disc 573 is installed on the output shaft of the hydraulic motor 572. One end of the overturning frame 575 is hinged to the eccentric disc 573, and the other end is hinged to the universal joint 574. The nozzle 58 is installed on the overturning frame 575. The overturning frame 575 is inclined and rotated at an angle of 5-10° with respect to the rotating axis of the output shaft of the hydraulic motor 572. Since the overturning frame 575 can be eccentrically and inclinedly rotated about the rotating axis of the hydraulic motor 572 with a conical trajectory, the nozzle 58 has one degree of freedom of eccentric and inclined rotation about the rotating axis of the hydraulic motor 572. Due to the above structure, the nozzle 58 has sufficient degrees of freedom, and the nozzle 58 can have the best spraying angle, thereby reducing the rebound rate of the concrete.
[0067] The utility model is described in detail below with reference to the drawings Figure 21 The drilling mechanical arms 60 are longitudinally arranged at the middle and both sides of the vehicle body 10. The drilling mechanical arms 60 have multi-degree-of-freedom telescopic drilling arms 61 and automatic feeding drilling machines 62. The drilling machines 62 can longitudinally drill holes and laterally drill holes. Therefore, the drilling mechanical arms 60 can replace the drill jumbo to drill holes and replace the rock bolting jumbo to drill anchor holes.
