Description

Technical Field

[0001] This utility model relates to the field of crane trolley technology, specifically a dustproof device for crane trolley tracks. Background Technology

[0002] A crane is a multi-action lifting machine that vertically lifts and horizontally moves heavy objects within a certain range. It plays a vital role in our production and daily life. In crane equipment, the trolley mechanism primarily drives the crane to reciprocate along the track of the crossbeam for lifting operations. The trolley plays a decisive role in the crane's lifting range and efficiency.

[0003] Currently, many crane equipment have open beam rails, which are easily contaminated by dust and particles in working environments, affecting the movement of the crane and making it difficult to use for extended periods.

[0004] Based on this, the present invention designs a dustproof device for crane trolley rails to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a dustproof device for crane travel rails to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dustproof device for a crane trolley track, comprising: a beam; a trolley is provided on the outer wall of the beam, and a telescopic sleeve is provided between the beam and the trolley;

[0007] The telescopic sleeve consists of multiple telescopic joints, and a joint ring is fixed between each telescopic joint. The joint ring is hollow and a copper alloy ring is fixed to its inner wall. The inner wall of the copper alloy ring is in contact with the beam. Each telescopic joint of the telescopic sleeve has a vent connector fixed to its outer wall, and one end of the vent connector is threaded and threaded to a filter cover.

[0008] Preferably, the outer wall of the filter cover has an opening, and an air filter is fixed inside the opening.

[0009] Preferably, the two ends of the telescopic sleeve are respectively locked and fixed to the crane and the beam rod by bolts.

[0010] Preferably, each end of the beam is connected to a support column, and the support column is locked to the connection end of the beam by bolts.

[0011] Preferably, a crane is fixed to the bottom of the crane.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the traveling track of the trolley on the beam is wrapped by two telescopic sleeves. The two telescopic sleeves extend and retract as the trolley moves, preventing dust and impurities from adhering to the traveling track of the beam and affecting the movement of the trolley. This makes it suitable for long-term operation in working environments with a lot of dust and particles.

[0014] Secondly, each expansion joint in the telescopic sleeve is equipped with a vent joint to ensure airflow to the outside, thereby balancing air pressure and reducing sleeve deformation or collapse. Furthermore, the connection of each expansion joint relies on a copper alloy ring to contact the beam. The bronze alloy copper alloy ring has good self-lubricating properties, making it suitable for sliding friction applications at the beam. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: a dustproof device for a crane trolley track, comprising: a beam 2; a trolley 3 is provided on the outer wall of the beam 2, and a telescopic sleeve 4 is provided between the beam 2 and the trolley 3;

[0024] The telescopic sleeve 4 is composed of multiple telescopic joints, and a joint ring 8 is fixed between each telescopic joint. The joint ring 8 is hollow and a copper alloy ring 9 is fixed on the inner wall of the ring. The inner wall of the copper alloy ring 9 is in contact with the beam rod 2. A vent joint 5 is fixed on the outer wall of each telescopic joint of the telescopic sleeve 4, and one end of the vent joint 5 is threaded and threaded to a filter cover 6.

[0025] The outer wall of the beam 2 is equipped with a track for the trolley 3 to move horizontally. A telescopic sleeve 4 is installed between the beam 2 and the trolley 3 to prevent dust from adhering to the track of the trolley 3 and affecting the trolley 3. The telescopic sleeve 4 uses each telescopic joint to expand and contract, cooperating with the reciprocating movement of the trolley 3. The joint ring 8 between the telescopic joints is supported and contacts the beam 2 by a copper alloy ring 9. The copper alloy ring 9 is made of bronze alloy, which has good self-lubricating properties and is suitable for long-term use. Each telescopic joint uses a vent joint 5 to ensure connection with the outside air to balance the air pressure, and uses a filter cover 6 to filter the circulating air to reduce impurities entering the telescopic sleeve 4.

[0026] More preferably, the outer wall of the filter cover 6 has an opening, and an air filter 7 is fixed inside the opening;

[0027] The opening of the filter cover 6 is connected to the threaded vent connector 5. The air filter 7 intercepts and filters impurities in the air entering the vent connector 5. It can be rotated and disassembled for replacement or cleaning.

[0028] More preferably, the two ends of the telescopic sleeve 4 are respectively locked and fixed to the crane 3 and the beam 2 by bolts;

[0029] Both ends of a telescopic leather sleeve 4 are rigid plates, which are locked and fixed by bolts, crane 3 and beam 2. The sleeve can be disassembled by removing the bolts.

[0030] More preferably, each end of the beam 2 is connected to a support column 1, and the support column 1 is locked to the connection end of the beam 2 by bolts;

[0031] The beam 2 and the support column 1 are fixed by bolts and can be disassembled and assembled, which can be used in conjunction with the telescopic sleeve 4 and the crane 3 for disassembly and assembly on the beam 2.

[0032] A further preferred embodiment is that a crane 10 is fixed to the bottom of the crane 3;

[0033] The overhead crane 3 is used to control the crane 10 at its bottom to move horizontally, assisting the crane 10 in lifting operations.

[0034] A specific application of this embodiment is as follows: the trolley 3 on the beam 2 moves horizontally, simultaneously driving the crane 10 at its bottom to move horizontally as well. During operation, the trolley 3 is located on the travel track of the beam 2 and is wrapped by two telescopic sleeves 4 to prevent dust and impurities from adhering and affecting the movement of the trolley 3. When the trolley 3 moves horizontally, it will cause the telescopic sleeves 4 at both ends to extend and retract, so that the telescopic sleeves 4 do not affect the normal horizontal movement of the trolley 3. Since frequent extension and retraction may cause changes in internal air pressure, each telescopic joint of the telescopic sleeve 4 is equipped with a vent joint 5 to ensure airflow with the outside, so as to balance the air pressure and reduce the deformation or collapse of the sleeve. The airflow is filtered by the air filter 7 of the filter cover 6 before entering the telescopic sleeve 4. Each telescopic joint contacts the beam 2 through the copper alloy ring 9 of the joint ring 8. The bronze alloy copper alloy ring 9 has good self-lubricating properties and is suitable for sliding friction at the beam 2.
