Description

Technical Field

[0001] This utility model belongs to the field of coal mine tunneling support technology, specifically relating to a temporary support device for front-probing beams used in tunneling support. Background Technology

[0002] In the excavation of the lower-level canopy roadway, the main method of using the unit's beam support device to support the canopy beam as temporary support is to frequently raise and lower the cutting head to adjust the position of the canopy beam. This operation has the following problems: First, the unit's long-term operation will cause the unit's oil temperature to rise, wear down the equipment, and increase the consumption of unit spare parts; Second, during the adjustment of the canopy beam's vertical legs, the use of the unit for adjustment, the personnel's positioning, and the linkage between the tunneling driver and the operator may lead to operator misoperation and injury. In the event of a failure in the unit's hydraulic system, the blasting head may fall, the temporary support will fail, and there is a risk of roof collapse and injury. Utility Model Content

[0003] This utility model addresses the problem that existing trapezoidal roof support systems in coal mines may cause injuries to personnel from the generating unit or roof collapses, by providing a temporary support device with a forward-probing beam for roof support.

[0004] The present invention adopts the following technical solution:

[0005] A temporary support device for scaffolding with forward-extending beams includes four forward-extending beam hanging devices. Each forward-extending beam hanging device includes a claw for connecting to a trapezoidal scaffolding beam. A connecting plate is connected to the bottom of the claw. One end of the connecting plate near the claw has a rectangular hole for inserting a pin, and the other end of the connecting plate has a round hole for inserting a movable pin. Two adjacent forward-extending beam hanging devices are connected by a pin and a movable pin. A π-shaped beam passes through the space between the pin and the movable pin.

[0006] Furthermore, the cross-section of the claw is C-shaped, and the upper end of the C-shape is shorter than the lower end.

[0007] Furthermore, a handle is provided on one side of the connecting plate.

[0008] Furthermore, the cross-section of the pin is a right-angled trapezoid.

[0009] Furthermore, the pin and the movable pin are connected by a chain.

[0010] The beneficial effects of this utility model are as follows:

[0011] This utility model uses claws to hold the top I-beam canopy beam in place, and inserts the π-shaped beam into the space between the pins and movable pins of the two adjacent forward-extending beam hanging devices. The π-shaped beam extends forward, thus supporting the next canopy beam as temporary support.

[0012] By using this utility model, the collapse of the roof can be effectively prevented, thus preventing injury to personnel from the unit. Attached Figure Description

[0019] The present invention will be further described with reference to the accompanying drawings.

[0020] As shown in the figure, a temporary support device for a canopy with a forward-extending beam includes four forward-extending beam hanging devices. Each forward-extending beam hanging device includes a claw 1 for connecting to a trapezoidal canopy roof beam. A connecting plate 2 is connected to the bottom of the claw 1. One end of the connecting plate 2 near the claw 1 is provided with a rectangular hole 3 for inserting a pin 5, and the other end of the connecting plate 2 is provided with a round hole 4 for inserting a movable pin 6. Two adjacent forward-extending beam hanging devices are connected by a pin 5 and a movable pin 6. A π-shaped beam 7 passes through the space between the pin 5 and the movable pin 6.

[0021] Furthermore, the cross-section of the claw 1 is C-shaped, and the upper end of the C-shape is shorter than the lower end.

[0022] Furthermore, a handle 8 is provided on one side of the connecting plate 2.

[0023] Furthermore, the cross-section of the pin 5 is a right-angled trapezoid.

[0024] Furthermore, the pin 5 and the movable pin 6 are connected by a chain.

[0025] A set of temporary support devices includes four forward beam suspension devices, two π-shaped beams with a length of not less than 2.5 meters, and each forward beam suspension device consists of a handle, a claw, a movable pin, and a pin. This specific combination of components forms a unique support structure.

[0026] The two claws are connected together by a movable pin and secured with a latch. This connection method ensures both the movable connection of the claws and the ability to be firmly fixed when needed, providing a foundation for subsequent support operations.

[0027] Temporary support is provided by using π-shaped beams to support the canopy beams. The claws are clamped onto the trapezoidal canopy beams and fixed with pins. Two forward-extending beam hanging devices are attached as a group and clamped onto the first and third canopy beams at the working face. The π-shaped beams are then passed through the two forward-extending beam hanging devices and used to push the canopy beams to the designated location to complete the temporary support.

[0028] For the support of trapezoidal roof beams, a specific combination of devices and operating procedures have been used to achieve efficient temporary support, which has unique applicability and innovation for the application of trapezoidal roof support.
