Description

Technical Field

[0001] This utility model relates to the field of coal mine electromechanical transportation technology, and in particular to coal mine electromechanical transportation lifting equipment. Background Technology

[0002] Coal mine electromechanical transportation refers to the transportation of coal, equipment, and personnel underground using electromechanical equipment. This process is crucial for ensuring coal mine production safety and improving production efficiency. However, in existing coal mine electromechanical transportation processes, the weight of coal, equipment, or personnel is often estimated visually, leading to inaccurate lifting weights and the risk of exceeding standard loads, which can damage the lifting equipment. While most coal mine electromechanical transportation does not use particularly large lifting equipment, small lifting equipment lacks sufficient lifting capacity, resulting in relatively low efficiency. Therefore, this paper proposes a new type of coal mine electromechanical transportation lifting equipment to address these issues. Utility Model Content

By driving a motor and a transmission chain to move the pallet, the support rods on both sides move, providing auxiliary support to the main lifting arm during the lifting process. This prevents the main lifting arm from being damaged due to excessive load at the moment of lifting off the ground. At the same time, it can increase the lifting weight of small lifting equipment and improve the efficiency of coal mine electromechanical transportation.

[0004] In a first aspect, this disclosure provides a coal mine electromechanical transport hoisting device, specifically comprising: a hoist and auxiliary components; a hoisting main boom is installed on the hoist; a sliding groove is formed on the top surface of the auxiliary components, and a transmission chain is installed on the auxiliary components; a locking block is slidably engaged inside the sliding groove; a support rod is welded to the top surface of the locking block; a telescopic tie rod is connected between the support rod and the auxiliary components, and a connecting plate is engaged between the bottom of the support rod; the connecting plate is fixedly connected to the transmission chain.

[0005] In at least some embodiments, a support plate is fixedly welded to the top of the two support rods. The support plate has an oblique groove, and the main lifting arm is engaged inside the oblique groove. The inner end of the engagement block is inserted into a groove inside the connecting plate.

[0006] In at least some embodiments, the transmission chain has a slot, the slot is rectangular and a card plate is inserted inside, and the connecting plate has slots on the left and right sides respectively.

[0007] In at least some embodiments, the top end of the telescopic rod is rotatably connected to a collar, the inside of which is fixedly connected to a support rod.

[0008] In at least some embodiments, a drive motor is fixedly mounted on the auxiliary component, and a drive shaft of the drive motor is connected to a rotating shaft by a transmission belt. A transmission chain is connected to the rotating shaft, and a rotating tube is sleeved on the rotating shaft on the side of the auxiliary component away from the drive motor. The rotating tube is fixedly connected to the fixed end of the telescopic rod. A protective box is fastened to the side of the auxiliary component and the outside of the drive shaft of the drive motor by bolts, and the transmission belt is placed inside the protective box.

[0009] This utility model provides a coal mine electromechanical transport and hoisting equipment, which has the following beneficial effects:

[0010] When in use, this utility model drives the rotating shaft to rotate via the drive motor and transmission belt, which in turn drives the transmission chain to rotate, moves the clamping plate, and causes the support rods on both sides to move. During the lifting process of the crane, it provides auxiliary support to the main lifting arm and avoids damage caused by excessive load on the main lifting arm at the moment of lifting off the ground.

[0011] It can also increase the lifting capacity of small lifting equipment and improve the efficiency of coal mine electromechanical transportation. Attached Figure Description

[0029] Example: Please refer to the appendix. Figure 1 To be continued Figure 6 :

[0030] This utility model proposes a coal mine electromechanical transportation hoisting equipment, including: a hoist 1 and an auxiliary component 2; a hoisting main boom 101 is installed on the hoist 1; a sliding groove 203 is opened on the top surface of the auxiliary component 2, and a transmission chain 4 is installed on the auxiliary component 2; a locking block 601 is slidably engaged inside the sliding groove 203; a support rod 6 is welded to the top surface of the locking block 601; a telescopic tie rod 3 is connected between the support rod 6 and the auxiliary component 2, and a connecting plate 5 is engaged between the bottom of the support rod 6; the connecting plate 5 is fixedly connected to the transmission chain 4.

[0031] In the embodiments disclosed herein, as shown in the appendix Figure 3 As shown, a collar 301 is rotatably connected to the top of the telescopic rod 3. The inside of the collar 301 is fixedly connected to the support rod 6. When the support rod 6 moves, it compresses the telescopic rod 3 to retract. At the same time, the angle change is satisfied through the connection with the rotating shaft. The telescopic rod 3 can provide auxiliary support for the support rod 6 and improve the stability of the support rod 6 when it moves.

[0032] In the embodiments disclosed herein, as shown in the appendix Figure 5As shown, a support plate 602 is fixedly welded to the top of the two support rods 6. An inclined groove is provided on the support plate 602. The main lifting boom 101 is engaged inside the inclined groove. The inner end of the locking block 601 is inserted into the locking groove inside the connecting plate 5. The locking block 601 is engaged with the auxiliary component 2 and is fixed in the left and right directions by the connecting plate 5. The support plate 602 provides auxiliary support for the main lifting boom 101.

[0033] In the embodiments disclosed herein, as shown in the appendix Figure 3 and attached Figure 6 As shown, the transmission chain 4 has a slot 401, which is rectangular and has a card plate 501 inserted inside. The connecting plate 5 has slots on both the left and right sides. When the rotating shaft rotates due to the drive of the drive motor 201 and the drive of the transmission belt 2021, it drives the transmission chain 4 to rotate. The card plate 501 moves through the slot 401, which in turn drives the support rods 6 on both sides to move, providing auxiliary support for the main lifting arm 101 during the lifting process of the crane 1.

[0034] In the embodiments disclosed herein, as shown in the appendix Figure 2 and attached Figure 4 As shown, a drive motor 201 is fixedly installed on the auxiliary component 2. The drive shaft of the drive motor 201 is connected to a rotating shaft via a transmission belt 2021. A transmission chain 4 is connected to the rotating shaft. A rotating tube 2022 is sleeved on the rotating shaft on the side of the auxiliary component 2 away from the drive motor 201. The rotating tube 2022 is fixedly connected to the fixed end of the telescopic pull rod 3. A protective box 202 is bolted to the side of the auxiliary component 2 and to the outside of the drive shaft of the drive motor 201. The transmission belt 2021 is placed inside the protective box 202. The protective box 202 protects the drive shaft of the drive motor 201 and the transmission belt 2021, preventing the working environment of coal mine transportation from reducing the service life of the drive motor 201. After the rotating shaft is driven to rotate by the transmission belt 2021, the transmission chain 4 can be driven to rotate, realizing power output.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In this invention, before lifting, the auxiliary component 2 is placed on the front side of the crane 1 and below the main lifting arm 101. The locking block 601 is engaged in the sliding groove 203, and the inner end of the locking block 601 is inserted into the slot inside the connecting plate 5. When lifting is in progress, the drive motor 201 is started to drive the rotating shaft to rotate through the transmission belt 2021. The transmission chain 4 rotates synchronously, which drives the connecting plate 5 to move and also drives the support rod 6 to move, supporting the bottom of the main lifting arm 101 and increasing the lifting weight.
