Description

Technical Field

[0001] The utility model belongs to the technical field of scraping and suction equipment, and in particular relates to a track anti-slip device and a truss type scraping and suction equipment. Background Art

[0002] Truss scraper is used in the horizontal flow sedimentation tank of sewage treatment plant to scrape the sludge settled at the bottom of the tank to the sludge collecting tank, and skim the floating scum on the surface of the tank to the slag collecting tank.

[0003] When the truss-type scraper and suction equipment is in operation, if there is a large amount of sludge at the bottom of the pool and the amount of sludge at both ends is uneven, the vibration of the truss-type scraper and suction machine will increase and the force on the left and right end beams of the scraper and suction machine will be uneven, causing the equipment to deviate, increase the friction between the four rollers and the track, and reduce the service life of the rollers. In severe cases, it will cause the equipment to climb and then derail.

[0004] If this device is installed in the above situation, the friction between the four rollers and the track will be reduced during the operation of the equipment. The guide wheel of the rail clamping and anti-slip device will play a role in correcting the deviation when it contacts the track. It greatly reduces the phenomenon of equipment derailment when climbing a slope. It reduces the probability of equipment damage. The device is installed at both ends of the end beam of the truss type equipment, which is easy to disassemble and install, simple to maintain and low cost. Utility Model Content

[0039] Example 1

[0040] like Figure 1-2 As shown, a track anti-slip device provided by the utility model is applied to be installed at the end of the end beam on the track, and the anti-slip device includes: a mounting plate, two bottom lining plates, an upper lining plate and two limiting wheels.

[0041] The mounting plate is vertically fixed to the end of the end beam, and two bottom lining plates are connected to the bottom of the mounting plate at intervals. The two bottom lining plates are respectively located on both sides of the track, and the bottom lining plates are horizontally arranged. One side of the bottom lining plates is connected to the mounting plate. The upper lining plate is located above the bottom lining plates and is connected to the mounting plate. Both ends of the upper lining plate are bent downward and covered and connected to the outside of the two bottom lining plates, forming an installation space covering the outside of the track between the bottom lining plates, and two limiting wheels are rotatably arranged in the installation space, and the axes of the limiting wheels are installed in the vertical direction. The circumferential surfaces of the two limiting wheels are relatively arranged with intervals between the sides of the track.

[0042] The limiting wheel is fixed in the installation space, the anti-slip device is located at the end of the end beam as a whole, two rotatably connected limiting wheels are arranged on both sides of the track, the distance between the two limiting wheels is greater than the width of the track, and the limiting wheels clamped on both sides of the track can prevent the end beam from shifting in the left and right lateral directions, and prevent the end beam from derailing from the track. The covering connection setting of the upper lining plate and the lower lining plate can form a semi-enclosed installation space with an opening in the front for the limiting wheel, so that the fixing effect of the limiting wheel, the mounting plate and the end beam is good, and the front end of the installation space is open, so the situation of the internal limiting wheel can be well seen, and it is convenient to clean the surroundings of the limiting wheel.

[0043] Specifically, a vertically arranged pin shaft is passed through the center of the limiting wheel, and both ends of the pin shaft are respectively connected to the upper lining plate and the lower lining plate to rotatably connect the limiting wheel in the installation space, and the limiting wheel is rotatably connected to the pin shaft.

[0044] To ensure that the pin is fixed stably and removable, positioning pieces are embedded in the circumferential surface of the two ends of the pin after passing through the upper lining plate and / or the lower lining plate. The positioning piece is fixedly connected to the upper lining plate and / or the lower lining plate to limit the axial displacement of the pin. Specifically, in this embodiment, a positioning piece is embedded in the end of the pin after passing through the upper lining plate, and the positioning piece is fixed to the upper lining plate so that the pin remains fixed; the lower end of the pin can also be fixed by the positioning piece after passing through the lower lining plate, or both ends of the pin can be embedded in the positioning piece for fixation. The diagram of this embodiment lists one representation.

[0045] In order to ensure the smooth rotation between the limiting wheel and the pin shaft, a bearing is arranged between the pin shaft and the limiting wheel, and a gasket is arranged between the limiting wheel and the upper lining plate and the lower lining plate. The gasket limits the up and down movement of the bearing, and the bearing can reduce the rotation friction between the limiting wheel and the pin shaft.

[0046] The upper lining plate and the bottom lining plate are fixed at the bottom of the mounting plate. In order to strengthen the structural strength between the upper lining plate and the bottom lining plate to form a whole and the mounting plate, a plurality of reinforcing ribs are arranged between the top of the upper lining plate and the mounting plate. There are two reinforcing ribs, both of which are located between the two pin shafts. The bottom of the reinforcing rib is fixed to the top of the upper lining plate, and the side is fixed to the surface of the mounting plate.

[0047] In order to improve the overall stability between the multiple reinforcing ribs, a reinforcing plate is arranged between the side of the reinforcing rib away from the mounting plate and the upper lining plate. The reinforcing plate is connected to several of the reinforcing ribs, and the reinforcing ribs, the reinforcing plate and the upper lining plate below are fixed to improve the overall stability and structural strength.

[0048] A connecting plate is connected between the mounting plate and the end of the end beam, and the connecting plate is fixed to the end of the end beam. A plurality of connecting holes are vertically spaced apart on the connecting plate, and the mounting plate is fixedly connected to the connecting plate through the connecting holes. The mounting plate and the connecting plate are connected and fixed by fasteners such as bolts passing through the connecting holes.

[0049] Example 2

[0050] like Figure 2 As shown, in this embodiment, different from Embodiment 1, two auxiliary wheels are also included. The two auxiliary wheels are arranged on the bottom lining plate on both sides of the track. The circumferential surface of the auxiliary wheels is used to contact the ground on both sides of the track. Specifically, the auxiliary wheels are shock-absorbing universal wheels. The circumferential surface of the auxiliary wheels is in contact with the ground to provide support from both sides to avoid the tipping of the end beams and to provide a better overall support effect. The shock-absorbing universal wheels are used to avoid uneven ground on which the tracks are set. The auxiliary wheels are fixed to the outer side of the upper lining plate through triangular brackets.

[0051] Multiple groups of connecting holes are arranged at vertical intervals on the connecting plate, so that the mounting plate and the upper lining plate, lower lining plate and limiting wheels connected to the mounting plate can be adjusted up and down in the vertical direction to make them suitable for end frames of different specifications, ensuring that the circumference of the limiting wheel corresponds to the side of the track to play a left and right lateral limiting role.
