Description

Technical Field

[0001] The utility model belongs to the technical field of cement processing equipment, in particular to a limiting device for a reclaimer. Background Art

[0002] There are four main raw materials required for cement processing: limestone, clay, iron ore and coal. The production process of cement processing can be divided into several steps, including mining, crushing, raw material storage and mixing, coal powder storage and mixing, batching, burning, cement grinding and cement packaging. In the mining process, limestone and clay need to be collected in a certain proportion, crushed and stored, and then mixed with coal powder. In the mineral storage and mixing process, a reclaimer is needed to transport raw materials. The reclaimer transports raw materials by moving on the track. During transportation, there is a risk of safety accidents caused by the collapse of the reclaimer track or the failure of the limit switch. The existing technology usually installs a limit block on the track. When the reclaimer slides out of control on the track, the limit block limits the moving wheel of the reclaimer to stop the reclaimer. However, when the limit block is rigidly connected to the track, the reclaimer will have a large inertia due to its own gravity and speed. At the moment when the reclaimer collides with the limit block, the reclaimer vibrates greatly, which can easily cause the material to fall or even damage the reclaimer and the track due to the large impact force. Utility Model Content

[0003] The purpose of the utility model is to provide a limiting device for a material reclaimer to solve the problems raised by the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a material grabber limiting device, comprising a base and a limiting block, the base being detachably connected to a moving track of the material grabber, the limiting block being slidably connected to the base, a baffle being vertically arranged on the base, a guide column being arranged on the limiting block, a through hole matching the guide column being arranged on the baffle, and the guide column being sleeved in the through hole on the baffle, a spring being transversely arranged between the baffle and the limiting block, and the spring being sleeved on the guide column.

[0005] Furthermore, the base is provided with a slot having the same sliding direction as the limit block, a plurality of groups of reinforcing ribs are provided below the slot, a card plate is provided at the lower part of the limit block, and the card plate is clamped below the slot, and the bottom surface of the card plate is in contact with the top surface of the moving track of the material extractor.

[0006] The limit block is clamped to the base through a clamping plate to prevent the limit block from being displaced in the vertical direction when the moving wheel of the material reclaimer collides with the limit block, affecting the braking effect, and reinforcing ribs are set at the clamping slot to avoid deformation of the clamping slot.

[0007] Furthermore, a cambered surface matching the moving wheel of the reclaimer is provided on the contact surface of the limit block with the moving wheel of the reclaimer.

[0008] An arc surface matching the moving wheel is arranged on the limit block to increase the contact surface between the limit block and the moving wheel, thereby further improving the braking effect.

[0009] Furthermore, a limiting ring is provided on the baffle protruding section of the guide column.

[0010] A limiting ring is provided to prevent the limiting block from being separated from the base under the action of the spring force.

[0011] Furthermore, a handle is provided on the base.

[0012] A handle is provided to facilitate carrying the device.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model realizes that the base and the limit block are slidably connected, and a spring buffer is arranged in the relative displacement direction of the base and the limit block. When the material reclaimer slides out of control on the track and the moving wheel contacts the limit block, the limit block slides under the impact of the moving wheel. When the limit block slides, the spring is compressed to absorb the kinetic energy of the movement of the material reclaimer, thereby reducing the vibration when the material reclaimer collides with the limit block, and avoiding the limit block and the moving wheel from rigidly contacting to damage the material reclaimer or the moving track of the material reclaimer.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The base 1 is provided with a handle 14 for facilitating the extraction of the device and a slot 12 in the same sliding direction as the limit block 2. A plurality of reinforcing ribs 13 are provided below the slot 12 to prevent the slot 12 from deforming. In order to prevent the limit block 2 from shifting in the vertical direction and affecting the braking effect, a card plate 22 is provided at the lower part of the limit block 2, and the card plate 22 is connected to the lower part of the slot 12. The bottom surface of the card plate 22 contacts the top surface of the moving track 4 of the material reclaimer. A baffle 11 is vertically provided on one side of the base 1, and a guide column is provided on the limit block 2. 21, a through hole matching the guide column 21 is provided on the baffle 11, and the guide column 21 is sleeved in the through hole on the baffle 11, a spring 3 is transversely provided between the baffle 11 and the limit block 2, and the spring 3 is sleeved on the guide column 21.
