Detailed Description
The utility model aims at solving the problem that tunneling materials (including accessories of a tunneling machine and materials required to be arranged in a tunnel) are difficult to be transported continuously and efficiently, and the basic technical concept of the utility model is to arrange an annular conveyor capable of continuously conveying long distances on a rear matched trailer so as to form an independent material transportation device, so that tunneling materials can be continuously transported forwards continuously along with forward tunneling of a host machine, and the material transportation efficiency is improved.
The present utility model is described in further detail below with reference to examples.
The embodiment 1 of the tunneling material conveying device provided by the utility model comprises the following components:
The tunneling material conveying device provided in this embodiment is shown in fig. 1-2, and includes a trailer 1, where an endless conveyor is provided on the trailer 1, and the endless conveyor refers to a conveyor with an endless traction member, and should not be understood as a conveying path having an endless shape. Specifically, the endless conveyor in the present embodiment is an endless belt conveyor, and as shown in fig. 1 to 6, the endless conveyor in the present embodiment includes a frame 2, a belt conveyor mechanism 3, and a drive system 4, which are integrally mounted on a trailer 1 through the frame 2.
As shown in fig. 4, the frame 2 includes a bracket 201, and the bracket 201 is a stress frame body with a certain strength, and is directly connected with the trailer 1. The belt conveyor 3 is integrally mounted on the support 201, specifically, the belt conveyor 3 includes a driving wheel 304, a driven wheel 301, and an annular traction member wound around the driving wheel 304 and the driven wheel 301, the driving wheel 304 is in transmission connection with the driving system 4, and can rotate under the driving action of the driving system 4, so as to drive the annular traction member to move, as shown in fig. 6, the driving system 4 in this embodiment includes a driving motor 401, a rotating shaft mounting frame 204 is provided on the frame 2, and a driving shaft 402 of the driving motor 401 passes through the rotating shaft mounting frame 204 and is connected with the driving wheel 304. The drive motor 401 is mounted on the drive mount 205, and the drive mount 205 may be provided on the frame 2 or may be provided directly on the trailer 1. The drive motor 401 may also be replaced with a hydraulic motor, as desired in the field.
Further specifically, the endless traction member in the present embodiment includes a traction chain 302, and correspondingly, the driving wheel 304 and the driven wheel 301 are sprockets, so that the strength is higher and the transportation process is more stable. In other embodiments, a traction belt (e.g., a synchronous belt) may be used as the endless traction member, where the primary pulley 304 and the secondary pulley 301 are pulleys. Of course, the endless traction member may also be a traction rope, and the driving wheel 304 and the driven wheel 301 are rope wheels.
In order to meet the requirement that the endless conveyor be able to convey material forward smoothly, the endless traction member should have a support structure for supporting and conveying the tunnelled material, in particular the support structure in this embodiment is formed by a conveyor belt attached to the traction chain 302. The tunneling material can be placed on the conveying belt, and the tunneling material is driven to move forwards by using the friction force between the surface of the conveying belt and the surface of the tunneling material. Of course, in other embodiments, the endless conveyor may also be configured in other forms, such as a chain conveyor with flights, where the support structure is formed by flights connected to a traction chain. Of course, if the annular traction member is a traction belt with a wider belt surface, the traction belt itself can form a supporting structure.
Considering that the individual tunneling materials are heavy, such as sleepers, a plurality of carrier rollers 203 are further provided on the frame 2 of the endless conveyor in this embodiment, as shown in fig. 4, the carrier rollers 203 are arranged at intervals in the conveying direction of the feeding, and the specific number and the interval between the adjacent two carrier rollers 203 are not particularly limited. The carrier roller 203 can play a role in supporting the conveyer belt, and no large friction force exists between the carrier roller 203 and the conveyer belt, so that the conveyer belt is safe and efficient. In other embodiments, if the conveyor belt is a relatively high-strength conveyor belt and the conveyed materials are all relatively light-weight heading machine accessories, the carrier roller 203 may not be configured, and the conveyor belt may be kept in a tensioned state or directly attached to the frame 2.
In addition, in order to increase the friction force between the conveying belt and the conveyed materials, as shown in fig. 5, the conveying belt in the embodiment is further provided with a plurality of protrusions which are also arranged at intervals along the circumferential direction of the conveying belt, and the protruding structures can increase the friction force between the conveyed materials and the surface of the conveying belt, so that the smooth conveying of the materials is ensured. Specifically, the bump structure in this embodiment is formed by the rubber block 303, the rubber block 303 is low in cost, can be integrally formed with the conveyor belt, and is easy to deform after being pressed, and the friction increasing effect is better. In other embodiments, the raised structures may be other materials, such as nylon, and the like. In other embodiments, a concave structure, such as grooves integrally formed with the conveyor belt, may also be provided on the conveyor belt.
In order to avoid that the conveyed material falls off from the annular conveyor, a guiding structure for being contacted and matched with the tunneling material to guide the tunneling material to tunnel forwards is further arranged in the embodiment. The guiding structures may be arranged on the left and right sides of the frame 2, or may be arranged on only one of the left and right sides, and when the material is placed, the guiding structures are placed on the side close to the side provided with the guiding structures. Specifically, the guiding structure in this embodiment is formed by a plurality of guiding rollers 202 arranged at intervals along the direction of conveying the material, and the contact friction between the guiding rollers 202 and the tunneling material is rolling friction, so that the resistance is smaller. In other embodiments, the guide structure may be a baffle.
Finally, regarding the connection relationship between the annular conveyor and the trailer 1, the annular conveyor in the embodiment is arranged on the outer side of the trailer 1, so that the space inside the trailer 1 can be saved, and the arrangement of the matched belt conveyor after slag discharge is facilitated. In order to improve the conveying efficiency, as shown in fig. 7, the endless conveyors in the present embodiment are arranged in pairs on the outer sides of the left and right sides of the trailer 1. Of course, in other embodiments, the endless conveyor may be provided inside the trailer 1, where space for the trailer 1 permits.
In order to facilitate the installation of the annular conveyor, the annular conveyor is directly installed on the support upright post 101 aiming at the trailer 1 with the support upright post 101, so that the conveying height of the annular conveyor is also facilitated to be reduced, and materials such as rail-laying materials and the like needing to be paved at the bottom of a tunnel are also facilitated to be conveyed. Of course, in other embodiments, the endless conveyor may be mounted on the equipment platform above the support columns 101.
When the continuous conveying system is particularly applied to a heading machine, a plurality of trailers 1 can be connected in series back and forth according to the requirement, so that a long continuous conveying system is formed. Of course, in some cases, such as straight driving conditions, it is also possible to provide the trailer 1 as a longer trailer 1, in which case there may be only one trailer 1.
The concrete embodiment 2 of the tunneling material conveying device provided by the utility model is mainly different from the embodiment 1 in that in the embodiment 1, the trailer 1 and the annular conveyor are matched in a one-to-one correspondence. In this embodiment, as shown in fig. 8, the tunneling machine material transporting apparatus includes a trailer group formed by at least two trailers 1 connected one after another, and the endless conveyor is provided on the trailer group, and specifically, the installation position and specific structure of the endless conveyor are consistent with those of embodiment 1 and will not be explained.
Specific embodiments of the heading machine of the utility model:
The heading machine includes a heading material transporting apparatus which is identical to the heading material transporting apparatus described in the above-described embodiment 1 or 2 of the heading material transporting apparatus, and will not be described in detail here.
It should be noted that the above-mentioned embodiments are merely preferred embodiments of the present utility model, and the present utility model is not limited to the above-mentioned embodiments, but may be modified without inventive effort or equivalent substitution of some of the technical features thereof by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
