Abstract
Description
Technical Field
[0001] The utility model belongs to the field of tunnel excavation, and in particular relates to a slag discharge device for a shield screw machine. Background Art
[0002] At present, subway construction sites are often restricted by the site because they need to work in cities. The starting working shaft of some shield machines is only 30-50 meters, while the length of the shield machines is 100 meters. Adding the length of the horizontal transport vehicle, the normal starting of the shield machine generally requires more than 150 meters of space. Due to the limited space length, the shield machine can only be started in a split manner. The split starting stage means that only the shield body of the shield machine can be lowered into the well, resulting in the inability to install the shield machine's slag conveyor. Without the installation of a belt conveyor to receive the soil, no device is installed at the spiral machine outlet, and a curtain is installed to block the mud. The slag falls directly from the spiral machine outlet below. Due to the insufficient length of the space below, only a small 3-5 cubic meter slag bucket can be used to load the soil, which greatly affects the construction efficiency and the progress of the construction period.
[0003] Therefore, how to propose a slag sluice device that facilitates the unearthing of a shield screw machine has become a problem that needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the utility model provides a shield screw machine excavation slag chute device for extending the position below the screw machine excavation port to facilitate parking of the dump truck. The excavation port of the utility model can be directly used for loading the large dump bucket of the dump truck, greatly improving construction efficiency.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a shield screw machine unearthed slag chute device, including an electric hoist and a chute channel, the middle part of the upper end surface of the chute channel is provided with a lifting lug, the electric hoist is arranged at the tail of the screw machine, and the hook of the electric hoist is hung on the lifting lug, the chute channel includes an arc cylinder and a rectangular cylinder, the arc cylinder is arranged on the screw machine, the head end of the rectangular cylinder is hinged to the arc cylinder and passed through the arc cylinder, and the end of the rectangular cylinder is provided with a vertical distance measuring device.
[0006] Furthermore, a rectangular flange is provided on the top of the rectangular cylinder, and the arc cylinder is fixed to the spiral excavation port of the screw machine through the flange.
[0007] Furthermore, a sealing gasket is provided at the rotation connection between the circular cylinder and the rectangular cylinder to prevent soil from leaking from the connection.
[0008] Furthermore, the outlet size of the rectangular cylinder is 700mm×900mm.
[0009] Furthermore, the vertical ranging device includes a hinge block, a weight block and a ranging sensor, the hinge block is arranged on the side wall of the end of the rectangular tube, the hinge block is rotatably connected to the rectangular tube, the weight block is arranged on the hinge block, and the ranging sensor is installed in the weight block.
[0010] The beneficial effects of the present invention are as follows: the present invention extends the position and length of the excavation port of the spiral machine through the setting of the slag chute device, which is convenient for the parking of the slag truck. The excavated soil is directly loaded into the 18-20 cubic meter large slag bucket of the slag truck, which greatly improves the construction efficiency. The slag chute can also use an electric hoist to adjust the excavation port up and down. The setting of the vertical distance measuring device can effectively measure the distance from the excavation port to the ground to prevent the excavation port from colliding with the slag truck. In this way, both large and small shield machines can be used. A pipe segment truck needs to be installed in front of the slag bucket truck for transporting the pipe segments, which also saves the time for lifting the pipe segments and the process of lifting the slag bucket truck to the ground and then lowering the pipe segment truck, which greatly improves the construction efficiency, speeds up the project progress, and saves costs for the project.

[0016] Example 1
[0017] like Figure 1-2 As shown, this embodiment discloses a shield screw machine excavation slag chute device, comprising an electric hoist 1 and a chute channel. The chute channel comprises a circular cylinder 2 and a rectangular cylinder 3. The circular cylinder 2 is mounted on the screw machine 9. The head end of the rectangular cylinder 3 is hinged to the circular cylinder 2 via a concentric axis 10 and is inserted into the circular cylinder 2, allowing the rectangular cylinder 3 to rotate along the concentric axis 10 without separating from the circular cylinder 2, thereby preventing soil leakage. The outlet size of the rectangular cylinder 3 is 700mm×900mm. A lifting lug 4 is provided in the middle of the upper end surface of the rectangular cylinder 3. The electric hoist 1 is mounted at the rear of the screw machine 9, and the hook of the electric hoist 1 is hung on the lifting lug 4. To prevent soil leakage from the connection, a sealing gasket is provided at the rotating connection between the circular cylinder 2 and the rectangular cylinder 3. The inclined extension section of the slag chute outlet can be adjusted in height using a chain hoist to meet different height requirements. When discharging slag, the slag outlet can be adjusted to be exactly level with the slag bucket to prevent mud and slag from splashing out.
[0018] As a preferred embodiment of the present utility model, a rectangular flange 5 is provided on the top of the rectangular cylinder 3 , and the arc cylinder 2 is fixed to the spiral outlet of the screw machine 9 through the rectangular flange 5 .
[0019] To measure the height of the end of the rectangular tube 3 from the ground, a vertical distance measuring device is installed at the end of the rectangular tube 3. The vertical distance measuring device includes an articulated block 6, a weight block 7, and a distance measuring sensor 8. The articulated block 6 is mounted on the side wall of the end of the rectangular tube 3 and is rotationally connected to the rectangular tube 3 via a bearing. The weight block 7 is mounted on the articulated block 6, and the distance measuring sensor 8 is installed in the weight block 7. The weight block 7 can be used to keep the distance measuring sensor 8 perpendicular to the ground at all times, thanks to the gravity of the weight block 7, so that the distance measuring sensor 8 can easily measure the height of the rectangular tube's excavation opening from the ground.
[0020] The manufacturing method of the present utility model is as follows: first measure the height of the spiral excavation port of the shield body, and design a slag chute of corresponding size according to the situation of the on-site shield machine. The length design of the slag chute needs to ensure that the slag outlet can cover the entire top of the slag truck, and the height design needs to ensure that the slag outlet can be higher than the slag bucket truck after lifting. Specifically, the chute channel is cut with 1cm thick steel plate as a whole, and finally welded into a slag chute in the shape of the figure. Finally, the vertical distance measuring device is installed, and the walkway plate is placed on the slag truck bucket and fixed. Then the prepared slag chute is hoisted down the well, placed on the slag truck, and sent to the spiral excavation port. The flange connection port of the slag chute is consistent with the spiral excavation port and is directly connected with bolts. In order to prevent the mud from leaking from the connection later, it is necessary to add a sealing gasket to the connection. In addition, a lifting lug 4 is welded at one-third of the slag chute port, and the electric hoist 1 chain is tightened. In this way, the installation is completed.
[0021] Although the above describes the specific implementation methods of the present invention in conjunction with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or variations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
