Description

Technical Field

The construction mechanism of the commonly used drilling rigs on the market is generally a fixed structure, that is, the working device is directly fixed in the existing position and cannot be changed. It can only pitch up and down and swing left and right. Such a structure makes the vehicle longer, increases the turning radius of the vehicle, and increases the difficulty of driving in and out of the tunnel. Moreover, in the case of a small tunnel section, due to the fixed relative position of the construction mechanism, it will also cause certain obstacles during operation, affecting construction efficiency.

DETAILED DESCRIPTION

[0044] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0045] like Figure 1 to Figure 3 As shown, a multi-arm tunnel construction trolley includes a vehicle body 1 and a plurality of construction mechanisms; a sliding mechanism is provided between the plurality of construction mechanisms and the vehicle body 1. A guide member is provided between the vehicle body 1 and the construction mechanism, and the guide member between at least one construction mechanism and the vehicle body 1 includes a slideway 2 provided on the vehicle body 1 and a pulley block 3 provided on the construction mechanism, and the slideway and the pulley block 3 are slidably matched.

[0046] In this embodiment, when the construction mechanism slides relative to the vehicle body 1, it moves smoothly along the extension direction of the sliding, thereby ensuring the safety and stability of the sliding. It is known that since the construction mechanism in the prior art cannot slide relative to the vehicle body 1 and its position is fixed relative to the vehicle body 1, its working surface is actually not large. After the sliding mechanism is set, the working surface can be well expanded, and on this basis, the length of the whole vehicle can be effectively reduced when the trolley enters and exits the tunnel, thereby reducing the turning radius, which is more conducive to the rapid movement of the trolley in the tunnel. Further, in order to make the guidance more stable, the slideway 2 is a concave structure arranged in the width direction of the vehicle body 1; the pulley group 3 includes a plurality of rollers, and the plurality of rollers are located in the concave structure. In this embodiment, the roller group includes a triangular plate and two rollers arranged side by side on the triangular plate. One corner of the triangular plate is connected to the construction mechanism, thereby on the basis of achieving guidance, it can well meet the support stability requirements of the construction mechanism.

[0047] like Figure 2As shown, in this embodiment, the sliding mechanism includes a driving chain 4 fixedly arranged on the vehicle body 1, a driving gear 5 rotatably arranged on the construction mechanism, and a power gear 6; the power gear 6 is used to drive the driving gear 5 to rotate. Specifically, the power gear 6 is arranged on the construction mechanism, and it has a motor for driving its rotation. When the driving gear 5 outputs power from the power gear 6, the driving gear 5 crawls along the driving chain 4, thereby driving the construction mechanism to move along the length direction of the driving rack, thereby realizing the adjustment of the length of the whole vehicle and thereby expanding the working area of ​​the construction mechanism.

[0048] In order to ensure the power output efficiency and stability of the chain gear mechanism, the sliding mechanism also includes a tensioning gear 7, which is located on one side of the driving gear 5 and is used to bend the driving chain 4 to increase the contact area between the driving gear 5 and the driving chain 4. Specifically, the tensioning gear 7 is set on the construction mechanism, and further, tensioning gears 7 are set on both sides of the driving gear 5. It can be seen that the driving gear 5 can be equipped with multiple pairs of tensioning gears 7. In this embodiment, a pair of tensioning gears 7 is taken as an example. A tensioning gear 7 is set on both sides of the driving gear 5. The two tensioning gears 7 cooperate with the driving gear 5, so that the driving chain 4 at this location is in a "J" shape. Therefore, for the driving gear 5, the arc length on the arc-shaped working part of its outer edge exceeds the semicircular arc length, so that the contact area between the driving gear 5 and the driving chain 4 is greatly guaranteed, so that the interaction force between the driving gear 5 and the driving chain 4 is larger and more, so it provides a good foundation for power output. It is known that in some other technical solutions of this embodiment, the sliding mechanism can also be a cylinder drive mechanism, a magnetic suspension mechanism, a gear rack mechanism, a linear motor mechanism, a screw nut mechanism, etc.

[0049] like Figure 1 , Figure 3 , Figure 4As shown, this embodiment includes three groups of construction mechanisms, which are arranged along the width direction of the vehicle body 1, one of which is located on the left, one of which is located on the right, and the last one is located in the middle, so that the three are respectively a left construction mechanism 8, a right construction mechanism 9 and a middle construction mechanism 10, wherein the left construction mechanism 8 and the right construction mechanism 9 are only provided with a rock drilling arm, and the middle construction mechanism 10 includes an intermediate arm support seat 11 that is slidably matched with the vehicle body 1, and the intermediate arm support seat 11 is provided with a first mounting portion 12 and a second mounting portion 13, and the first mounting portion 12 is located above the second mounting portion 13; the first mounting portion 12 is used to install the intermediate auxiliary arm, and the second mounting portion 13 is used to install the intermediate construction arm. The middle construction mechanism 10 is arranged with a height difference between the upper and lower parts as a whole, and different working devices can be configured according to the needs of the operation function. Specifically in this embodiment, the left construction mechanism 8, the right construction mechanism 9 and the middle construction mechanism 10 are all configured as rock drilling mechanisms. It is known that in some other embodiments, they can also be configured as arch transport mechanisms, concrete spraying mechanisms, grouting mechanisms, etc. In this embodiment, in addition to the normal boom movement, the left construction mechanism 8, the right construction mechanism 9 and the middle construction mechanism 10 can also slide along the length direction of the vehicle body 1. When the trolley is driving normally, they can slide to a position that reduces the overall length of the trolley, thereby reducing the turning radius of the vehicle and making the driving passability better. Moreover, the sliding movement of the left construction mechanism 8, the right construction mechanism 9 and the middle construction mechanism 10 can realize the redistribution of the front and rear axle loads of the vehicle, thereby optimizing the front and rear axle loads and extending the service life of the axles. Based on this, especially when using the rock drilling mechanism for step method construction, all construction mechanisms can be slid to the rear of the trolley, the trolley is parked at a position close to the steps, and then the construction mechanism is tilted upward and slid to the front of the trolley, and then the posture of the construction mechanism is adjusted to perform the operation, thereby well solving the problem of interference between the construction mechanism and the steps caused by the relatively fixed position between the construction mechanism and the vehicle body 1 in the prior art. In addition, it should be noted that, in the present embodiment, the left construction mechanism 8 and the right construction mechanism 9 are both slidably connected to the vehicle body 1 by means of a slideway cooperating with the pulley block 3, and for the middle construction mechanism 10, in order to save assembly space and / or simplify the assembly structure, it is slidably connected to the vehicle body 1 by means of a slider and a slide rail component. Specifically, the vehicle body 1 is provided with a slide rail, and the middle construction mechanism 10 is provided with a slider 22 cooperating with the slide rail.

[0050] like Figure 1As shown, in this embodiment, it also includes a traveling mechanism, a cab 14 and a cab 2 15; the traveling mechanism is used to drive the vehicle body 1 to move forward; the cab 1 14 is arranged at the front end of the vehicle body 1; the cab 2 15 is arranged at the rear end of the vehicle body 1; the driving systems arranged in the cab 1 14 and the cab 2 15 are connected to the traveling mechanism. The cab 1 14 and the cab 2 15 are arranged at the front and rear positions of the vehicle body 1 respectively, so that when the trolley enters and exits the tunnel, the driver can choose the corresponding cab to obtain a good driving field of view and ensure driving safety. In order to improve the space utilization rate of the vehicle body 1, in this embodiment, a reel 16 is arranged on one side of the cab 2 15. The reel 16 can realize the winding and unwinding of water pipes and cables, so as to better meet the storage requirements. In some embodiments, the number of the reels 16 is two, and the two reels 16 are arranged side by side for winding and unwinding water pipes and cables respectively. The cables and water pipes are usually used for rock drilling and connecting the trolley to the mains. In different working scenarios, the two are not necessarily used at the same time. Therefore, in actual working conditions, construction personnel can choose to use different reels 16 according to actual selection, which is more convenient for actual operation.

[0051] In the present embodiment, a working device is provided on the construction mechanism; at least one construction mechanism is also provided with a liftable operating platform 17. The working device is the above-mentioned working arm, and the operating platform 17 is used to control the working arm. Specifically, in the present embodiment, the left construction mechanism 8 and the right construction mechanism 9 are provided with a liftable operating platform 17, and the middle construction mechanism 10 can be controlled through the operating platform 17 on the left construction mechanism 8 and / or the right construction mechanism 9. In order to lower the height of the entire vehicle when the trolley is traveling and to protect construction personnel during operation, a liftable ceiling 18 is provided on the operating platform 17. In the present embodiment, the mechanism that makes the operating platform 17 liftable and the mechanism that makes the ceiling 18 liftable can be the same or different. Generally, a rack and pinion mechanism, a cylinder mechanism, a linear motion mechanism, etc. can be used. The present embodiment uses a cylinder mechanism for illustration. Taking the ceiling 18 as an example, Figure 5 As shown, the cylinder mechanism includes an outer cylinder 19, an inner cylinder 20, and a lifting cylinder 21. The outer cylinder 19 is fixedly connected to the operating table 17, and the inner cylinder 20 is fixedly installed on the ceiling 18. The inner cylinder 20 can be inserted into the outer cylinder 19, and there is a certain gap between the inner cylinder 20 and the outer cylinder 19. The lifting cylinder 21 is used to drive the inner cylinder 20 to move, so that the inner cylinder 20 can move up and down relative to the outer cylinder 19 under the action of the lifting cylinder 21, so that the ceiling 18 can be raised and lowered relative to the operating table 17. It is known that in some other embodiments, the arrangement and driving method of the inner cylinder 20 and the outer cylinder 19 can be opposite to that of this embodiment.

[0052] Therefore, through this embodiment, the construction mechanism is equipped with a sliding mechanism. When the trolley enters and exits the tunnel, the construction mechanism is driven to slide, which can reduce the overall length of the vehicle, thereby reducing the turning radius of the trolley and improving driving performance; and the load on the front and rear axles of the trolley can be redistributed and optimized, thereby extending the service life of the axles. At the same time, the rock drilling operation area is expanded, the construction efficiency is improved, and the problem of interference between the construction mechanism and the steps is well solved.

[0053] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
