Description

Technical Field

[0001] This utility model belongs to the field of coal mine tunneling and fully mechanized mining technology, and in particular relates to a tracked temporary support device. Background Technology

[0002] In coal mine tunneling faces or fully mechanized mining roadways, temporary support is a crucial link in ensuring construction safety and preventing loose and falling roof rocks from injuring personnel and equipment. Traditional temporary support usually uses fixed bases or simple mobile chassis, which have poor mobility and flexibility. Moving and positioning them in the narrow space underground is cumbersome and time-consuming, which seriously affects the efficiency of tunneling operations.

[0003] In addition, the top support range of these devices is mostly fixed, which has poor applicability and may have blind spots, so safety needs to be improved. Furthermore, they cannot be retracted when the equipment is moved, which not only affects the passage, but also makes it difficult to achieve a tight fit with well walls of different inclination angles, thus greatly reducing the protective effect.

[0004] In terms of lifting methods, common equipment often uses single-stage hydraulic cylinders for direct lifting. In order to meet the support height requirements, the stroke of such hydraulic cylinders must be designed to be very long. Long-stroke hydraulic cylinders are not only expensive to manufacture and bulky, but also need to be fully retracted after completing a support cycle before they can be moved to the next work position. The entire retraction process takes a long time, which seriously restricts the rhythm of the excavation and masonry cycle operation.

[0005] Meanwhile, the existing equipment has insufficient stability and leveling capabilities. On uneven well bottom working faces, the equipment is prone to shaking, affecting the reliability of the support. Its operation method is also relatively traditional, usually requiring personnel to operate close to the equipment, failing to effectively achieve human-machine isolation, and still posing a potential threat to the safety of operators. Summary of the Invention

[0006] The purpose of this utility model is to provide a tracked temporary support device. It moves via a tracked walking unit and features a three-layer composite frame design. This allows the upper frame to be adjusted in width, left and right angles, and front and rear height, enabling rapid adjustment of the protection position and area. The telescopic adjustment function at the front end of the upper frame allows for the extension and expansion of the protection area without driving the tracked walking unit, thereby reducing support relocation time and improving protection efficiency. In addition to meeting the requirements for top support, it also provides a gap for anchor bolt installation, which is beneficial for subsequent permanent support operations such as anchor bolts and anchor cables.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a tracked temporary support device, including a composite frame and a set of symmetrically arranged tracked walking parts; The upper guard is fixed to the rear end of the track walking part.

[0008] Furthermore, the protective nets on both sides and the front of the upper frame are each composed of several mesh panels, and each mesh panel is equipped with a folding hydraulic cylinder between itself and the upper frame.

[0009] Furthermore, the mesh body includes an outer frame, a metal mesh is provided inside the outer frame, a T-shaped edge is provided in the middle of the outer frame, a lower support lug is provided on the back of the T-shaped edge to be connected to the folding oil cylinder, and an upper support lug is provided on the top edge of the outer frame to be connected to the upper frame.

[0010] Furthermore, the tracked traveling unit consists of a frame and a hydraulic track assembly, the upper guard is fixed to the rear end of the frame, and the vertical box is fixed to the front end of the frame.

[0011] Furthermore, the cylinder seat end of the main lifting cylinder is fixedly installed on the top of the vehicle frame, and upper hinge seats are fixed at the bottom of the four corners of the lower frame. The telescopic rod end of the main lifting cylinder is rotatably connected to a lower hinge seat.

[0017] This utility model has the following beneficial effects: 1. This utility model uses a tracked walking unit for movement and a three-layer composite frame design to enable the upper frame to adjust its width, left and right angles, and front and rear height. This allows for quick adjustment of the protective position and area. The telescopic adjustment function at the front end of the upper frame allows for the extension and expansion of the protective area without driving the tracked walking unit, thereby reducing support relocation time and improving protection efficiency. In addition to meeting the requirements for top support, it also leaves a gap to allow for anchor bolt installation, which is beneficial for subsequent permanent support operations such as anchor bolts and anchor cables.

[0018] 2. This utility model uses a double-track walking unit as the walking mechanism, which has strong driving force and low ground pressure. It can walk stably and turn flexibly in the harsh environment of uneven well bottom, which greatly facilitates the rapid relocation and precise positioning of equipment on the working face and overcomes the shortcomings of poor flexibility of fixed or simple mobile chassis.

[0019] 3. This utility model adopts a two-stage lifting design that combines a main lifting cylinder and an auxiliary lifting cylinder. The main lifting cylinder is responsible for adjusting the height range to adapt to the well depth requirements of different tunneling sections. The auxiliary lifting cylinder is used for small-amplitude rapid retraction during repositioning. This design avoids the problems of high manufacturing cost and long retraction time caused by using a single ultra-long stroke cylinder. During repositioning, only a small downward movement of the auxiliary lifting cylinder is needed to allow the device to detach from the top plate, then move, and then quickly lift again after reaching the position, which greatly shortens the auxiliary time in the support cycle.

[0020] 4. The flip-type hydraulic leg at the rear end of the tracked walking section and the vertical hydraulic leg at the front end of this utility model constitute a multi-point support system. During operation, the hydraulic legs extend and together with the track to form a stable support, evenly transferring the weight of the equipment to the foundation, effectively suppressing swaying during operation, and ensuring the absolute stability and reliability of the support process. This design is especially suitable for inclined or uneven working surfaces. The precise leveling of the entire device can be achieved through the independent adjustment of each leg.

[0021] 5. This utility model achieves remote control of the equipment by integrating a valve group system and equipping it with both manual and remote control operation modes. Operators can control all the actions of the equipment from a safe distance, completely avoiding the risks of working under an open ceiling or in a dangerous area, and truly realizing the modern safety construction concept of "safety without human intervention".
