Description

Technical Field

[0001] The utility model belongs to the technical field of support equipment for gob-side entry retaining in coal mines, and particularly relates to a side support mechanism of a formwork hanging device. Background Technique

[0002] In China, coal resources are mainly mined by underground mining methods. With the continuous increase in mining intensity and the gradual reduction of coal resources year by year, the problems faced by the traditional gob-side entry retaining method using coal pillar protection in longwall fully mechanized mining faces in coal mines are becoming increasingly prominent: on the one hand, it causes a large amount of coal resource loss; on the other hand, leaving sectional coal pillars requires a large amount of driving of return airways, which to a certain extent exacerbates the imbalance between excavation and mining ratios. To reduce resource loss and alleviate the excavation-mining imbalance, more and more mines use the technology of gob-side entry retaining with flexible formwork concrete walls during mining, that is, self-compacting concrete with adjustable setting time and strength is injected into the once-precast flexible formwork that has been hung, forming a tightly connected top flexible formwork concrete continuous wall between the goaf and the return airway, continuing to serve the next working face, and canceling the traditional gob-side coal pillar. The applicant applied for a utility model patent named "Mechanized Formwork Hanging Device" with the patent number 202220215516.8 in 2022. This formwork hanging device has been applied in multiple mines, improving the formwork hanging efficiency, reducing the number of operating personnel, and enhancing the technical equipment level of the flexible formwork gob-side entry retaining technology.

[0003] At present, the formwork hanging devices used for flexible formwork gob-side entry retaining have good application effects under the condition of low undulation of the application roadway. However, in inclined coal seams, when the floor undulates unevenly, the following situations are likely to occur: (1) When the ordinary formwork hanging device is applied in an inclined coal seam, the base of the formwork hanging device is prone to tilt. Although there is a tensioning oil cylinder control, it is still prone to tilt. (2) When the existing formwork hanging device is used on an uneven floor, the flexible formwork is prone to deviation during hanging, resulting in the flexible formwork being obliquely hung. After filling with concrete, the wall is inclined and the gob-side entry retaining effect is not good. (3) During the forward movement and recovery process of the existing formwork hanging device, there is no side support device, so it is prone to deviation and cannot recover by itself subsequently, affecting the formwork hanging and flexible formwork pouring processes during the gob-side entry retaining process. Therefore, it is necessary to design a side support mechanism for the formwork hanging device to solve the problems of easy deviation and tilt of the formwork hanging device when the floor is uneven. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a side support mechanism for a formwork hanging device to solve the problems of inclination and deviation of the formwork hanging device caused by the uneven floor and roof pressure during the implementation of flexible formwork concrete gob-side entry retaining.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a side support mechanism for a formwork hanging device, including a formwork hanging device base, a pair of side support seats, and a pair of reciprocating driving mechanisms; the pair of side support seats are respectively hinged on both sides of the formwork hanging device base, the bases of the pair of reciprocating driving mechanisms are hinged on the corresponding side support seats, and the driving ends of the reciprocating driving mechanisms are hinged on the formwork hanging device base.

[0006] As a preferred technical solution of the present utility model, a plurality of first hinge seats and a plurality of second hinge seats are arranged on the base of the form hanging device. A first pin shaft is arranged in each of the first hinge seats, and a second pin shaft is arranged in the second hinge seats. The driving end of the reciprocating driving mechanism is sleeved on the corresponding first pin shaft, and the side support seat is sleeved on the corresponding second pin shaft.

[0007] As a preferred technical solution of the present utility model, each of the side support seats is sleeved on a plurality of second pin shafts.

[0008] As a preferred technical solution of the present utility model, a third hinge seat is arranged on the side support seat, and a third pin shaft is arranged in the third hinge seat. The base of the reciprocating driving mechanism is sleeved on the third pin shaft.

[0009] As a preferred technical solution of the present utility model, the reciprocating driving mechanism is a jack.

[0010] The beneficial effects of the present utility model are as follows: (1) For the side support mechanism of the form hanging device of the present utility model, side support jacks are installed on both sides of the base, which can solve the problem that the form hanging device for inclined coal seams is prone to tilt, reduce the risk of the form hanging device tilting, enhance the stability of the form hanging device, and achieve efficient flexible form hanging during the process of gob-side entry retaining layout. (2) For the side support mechanism of the form hanging device of the present utility model, the side support seat and the base of the form hanging device are hinged through the side support jack, and can be adjusted by the oil cylinder when the form hanging device deviates, so as to correct it and ensure that the flexible form wall is perpendicular to the roadway floor without tilting. (3) For the side support mechanism of the form hanging device of the present utility model, a hydraulic jack is used as the connecting piece between the side support seat and the base of the form hanging device, so that the flexible form hanging device can move horizontally, and improve the efficiency of flexible form hanging in the construction of gob-side entry retaining with flexible form concrete.

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0017] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, and connection should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0018] Embodiment 1

[0019] As Figure 1 shown, a side support mechanism of a formwork hanging device of the present invention includes a base 1 of the formwork hanging device, a pair of side support seats 6, and a pair of reciprocating drive mechanisms 3. The pair of side support seats 6 are respectively hinged on both sides of the base 1 of the formwork hanging device, the bases of the pair of reciprocating drive mechanisms 3 are hinged on the corresponding side support seats 6, and the drive ends of the reciprocating drive mechanisms 3 are hinged on the base 1 of the formwork hanging device.

[0020] As Figure 1 , Figure 2 and Figure 3 shown, the present invention is a side support mechanism of a formwork hanging device. By hinging the reciprocating drive mechanisms 3 on the base 1 of the formwork hanging device and the side support seats 6 respectively, the three are connected into a whole, and its structure is simple and has a side support effect.

[0021] During the formwork hanging operation along the gob-side entry retaining, when the formwork hanging device deviates, operate the expansion and contraction of the reciprocating drive mechanism 3. Relying on the mutual acting force between the reciprocating drive mechanism 3 and the base 1 of the formwork hanging device, move the base 1 of the formwork hanging device to the left or right, and then guide the force to the side support seat 6 through the reciprocating drive mechanism 3 to complete a lateral movement. The reciprocating drive mechanisms 3, the base 1 of the formwork hanging device, and the side support seats 6 are all assembled together by hinges to form a whole, which not only ensures that the formwork hanging device can adapt to different floor undulations, but also always keeps the formwork hanging device from deviating, and can achieve the goal of efficient formwork hanging.

[0022] As Figure 1 shown, the present invention is a side support mechanism of a formwork hanging device. By assembling the base 1 of the formwork hanging device and the side support seats 6 through the reciprocating drive mechanism 3, the anti-tilting ability of the formwork hanging device is improved, and the formwork hanging device is prevented from deviating. From Figure 3As can be seen, a stable triangular structure is formed between the reciprocating drive mechanism 3, the base 1 of the die-hanging device, and the side support seat 6. When the die-hanging device faces the complex floor conditions of an inclined coal seam, the influence of the undulating floor on the base of the die-hanging device will be reduced by the side support jacks, enhancing the ability of the die-hanging device to work under complex floor conditions and its anti-tilt ability, enabling the die-hanging device to have the ability of lateral movement and automatically correcting the deviation of the die-hanging device.

[0023] Combined with Figure 3 As shown, the reciprocating drive mechanism 3 is hinged to the base 1 of the die-hanging device through the upper drive end and hinged to the side support seat 6 through the lower base, forming an integral whole for the upper and lower parts. It can effectively provide a lateral force to the die-hanging device, which can not only control the lateral movement of the die-hanging device but also enhance the anti-tilt ability of the die-hanging device on complex terrains.

[0024] Therefore, compared with the prior art, the present utility model has the following advantages: (1) For the side support mechanism of a die-hanging device of the present utility model, side support jacks are installed on both sides of the base, which can address the problem that the die-hanging device of an inclined coal seam is prone to tilting, reducing the risk of tilting of the die-hanging device and enhancing the stability of the die-hanging device to achieve efficient flexible mold hanging during the process of gob-side entry retaining layout. (2) For the side support mechanism of a die-hanging device of the present utility model, the side support seat and the base of the die-hanging device are hinged through side support jacks, which can automatically correct when the die-hanging device deviates, ensuring that the flexible mold wall is perpendicular to the roadway floor without tilting. (3) For the side support mechanism of a die-hanging device of the present utility model, a hydraulic jack is used as the connecting piece between the side support seat and the base of the die-hanging device, enabling the flexible mold hanging device to move laterally and improving the efficiency of flexible mold hanging in the construction of gob-side entry retaining with flexible mold concrete.
