Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a bridge deck crawler walking protection structure. Background Art
[0002] With the continuous development of social economy, there are more and more bridges across rivers, rivers and seas, especially cross-sea bridges, most of which are super-large bridges over 10km. The necessary supporting facilities for completing these super projects are trestles. The complex corrosion environment in the sea area is particularly prominent for the corrosion of steel, so the bridge deck of the trestles is made of reinforced concrete bridge deck to resist the corrosive environment of the sea. During the construction process, when the crawler equipment walks on the bridge deck, because the bottom area of the support strip of each crawler plate is relatively small, under the greater gravity of the equipment, the support strip squeezes the bridge deck, causing greater damage to the bridge deck, and each walk will cause damage. Under the repeated walking of the crawler equipment, the speed of damage to the bridge deck is seriously aggravated. Summary of the invention
[0003] In order to solve the above problems, the purpose of the utility model is to provide a bridge deck crawler walking protection structure, which installs the protection device on the groove of the crawler. After the pad is squeezed, it is flush with the walking surface of the crawler. The deformed pad and the crawler are subjected to force together, forming a flexible contact between the crawler and the bridge deck, increasing the contact area between the crawler and the bridge deck, and reducing the damage of the crawler equipment to the reinforced concrete bridge deck. At the same time, the protection device has a simple structure, is easy to manufacture, and is safe and reliable to construct. It can be processed to a fixed length according to the width and thickness of the crawler of different equipment and used in combination, and has a wide range of applications.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:
[0005] The crawler plate is connected to the track plate by a plurality of connected track shoes, wherein two support strips are extended outwardly on the track plate, a groove is formed between the two support strips, and the upper end surfaces of the plurality of support strips form the walking surface of the track, and the characteristic is that a protective device is provided on the groove, and the protective device comprises a pad and a clamping plate arranged on both sides of the pad; the pad is installed in the groove, the outer end surface of the pad extends out of the walking surface of the track, and the two sides of the pad are flush with the side ends of the groove; the clamping plate is an L-shaped plate, comprising a short plate fixed to the side wall of the pad and extending downward, and a long plate extending and formed under the pad, a clamping groove is formed between the short plate, the long plate and the pad, and the side portion of the corresponding groove on the track plate is constructed as a clamping wall that is adapted to be clamped with the clamping groove, and the pad can be deformed under the action of external force so that the outer end surface of the pad is flush with the walking surface of the track.
[0006] In the above technical solution, a groove is formed between the two support strips on each track shoe, and the pad of the protective device is arranged in the groove. The pad can be deformed under the action of external force so that the outer end surface of the pad is flush with the running surface of the track. Therefore, when the outer end surface of the pad is in contact with the bridge deck, it is squeezed and flush with the running surface of the track, and a flexible contact is formed between the pad and the bridge deck, and the contact surface between the track and the bridge deck is increased, which greatly reduces the damage of the track-type equipment to the reinforced concrete bridge deck. In addition, a card plate is arranged on both sides of the pad plate, which is L-shaped and can be stuck on the card wall on both sides of the track shoe to prevent the protective device from rotating radially relative to the groove, improve the assembly stability of the pad plate, and prevent it from detaching from the groove.
[0007] Preferably, the cross-section of the groove and the pad is in a matching trapezoidal shape, and the upper end of the cross-section is wider than the lower end. In this technical solution, the cross-section of the groove and the pad is in a matching trapezoidal shape, thereby making the pad area in contact with the ground on a track shoe larger, the flexible contact surface is large, and the damage to the bridge deck is further reduced.
[0008] Preferably, the pad is a rubber block. In this technical solution, the rubber block has good deformation ability, good resilience, heat resistance and corrosion resistance, can adapt to the bridge deck environment well, and is set on the track to play a good protective effect on the bridge deck. In addition, the pad can also be made of other elastic materials, such as polyurethane materials.
[0009] Preferably, the length of the pad is adapted to the length of the groove, and the inner wall of the short plate abuts against the card wall. In this technical solution, the length of the pad is adapted to the length of the groove, and the inner wall of the short plate abuts against the card wall, so that the pad can be prevented from shaking left and right during use, and the card can also be prevented from being detached from the left and right, thereby improving the assembly stability of the protective device on the track.
[0010] Preferably, the short plate is fixedly connected to the backing plate by a plurality of anchor bolts. In this technical solution, the short plate on the clamping plate is fixed to the backing plate by a plurality of anchor bolts, so that the short plate is anchored and connected to the backing plate, and the connection strength is high, so that the integrity of the clamping plate and the backing plate is good, and the stability of the backing plate is further improved.
[0011] Preferably, the width of the long plate is the same as the width of the pad. In this technical solution, after the clamping plate and the clamping wall are engaged, the long plate fits under the track shoe. The width of the long plate is the same as the width of the pad, which can maximize the fitting area between the long plate and the bottom surface of the track shoe, making the clamping effect of the clamping plate better and effectively preventing the clamping plate from being disengaged.
[0012] Preferably, the upper end of the short board is lower than the upper end of the support bar. In this technical solution, the upper end of the short board is lower than the upper end of the support bar and lower than the upper end surface of the pad, so as to prevent the pad from contacting the ground after deformation and causing the short board to contact the ground, thereby avoiding damage to the structure of the cardboard.

Embodiment 1:
[0021] like Figures 1 to 3 A bridge deck crawler walking protection structure shown in the figure comprises a crawler, and the crawler comprises a plurality of connected track plates 1, two support strips 2 extending outwardly from the track plates 1, a groove 3 being formed between the two support strips 2, and the upper end surfaces of the plurality of support strips 2 forming the walking surface of the crawler, and a protective device is provided on the groove 3, and the protective device comprises a pad 4 and a clamping plate 5 arranged on both sides of the pad 4; the pad 4 is installed in the groove 3, the outer end surface of the pad 4 extends out of the walking surface of the crawler, and the two sides of the pad 4 are flush with the side ends of the groove 3; the clamping plate 5 is an L-shaped plate, comprising a short plate 6 fixed to the side wall of the pad 4 and extending downward, and a long plate 7 extending and formed below the pad 4, a clamping groove 8 is formed between the short plate 6, the long plate 7 and the pad 4, and the side portion of the track plate 1 corresponding to the groove 3 is constructed as a clamping wall 9 adapted to be clamped with the clamping groove 8, and the pad 4 can be deformed under the action of external force so that the outer end surface of the pad 4 is flush with the walking surface of the crawler.
[0022] In the above technical solution, a groove is formed between the two support strips on each track shoe, and the pad of the protective device is arranged in the groove. The pad can be deformed under the action of external force so that the outer end surface of the pad is flush with the running surface of the track. Therefore, when the outer end surface of the pad is in contact with the bridge deck, it is squeezed and flush with the running surface of the track, and a flexible contact is formed between the pad and the bridge deck, and the contact surface between the track and the bridge deck is increased, which greatly reduces the damage of the track-type equipment to the reinforced concrete bridge deck. In addition, a card plate is arranged on both sides of the pad plate, which is L-shaped and can be stuck on the card wall on both sides of the track shoe to prevent the protective device from rotating radially relative to the groove, improve the assembly stability of the pad plate, and prevent it from detaching from the groove.
[0023] Furthermore, the cross-sections of the groove 3 and the pad 4 are in a matching trapezoidal shape, and the upper end of the cross-section is wider than the lower end. In this technical solution, the cross-sections of the groove and the pad are in a matching trapezoidal shape, thereby making the pad area in contact with the ground on a track shoe larger, the flexible contact surface is large, and the damage to the bridge deck is further reduced.
[0024] Furthermore, the pad 4 is a rubber block. In this technical solution, the rubber block has good deformation ability, good resilience, heat resistance and corrosion resistance, can adapt to the bridge deck environment well, and is set on the track to play a good protective effect on the bridge deck. In addition, the pad can also be made of other elastic materials, such as polyurethane materials.
[0025] Furthermore, the length of the pad 4 is adapted to the length of the groove 3, and the inner wall of the short plate 6 abuts against the card wall 9. In this technical solution, the length of the pad is adapted to the length of the groove, and the inner wall of the short plate abuts against the card wall, so that the pad can be prevented from shaking left and right during use, and the card can also be prevented from being disengaged from left and right, thereby improving the assembly stability of the protective device on the track.
[0026] Furthermore, the short plate 6 is fixedly connected to the pad 4 by a plurality of anchor bolts 10. In this technical solution, the short plate on the cardboard is fixed to the pad by a plurality of anchor bolts, so the short plate is anchored and connected to the pad, and the connection strength is high, so that the integrity of the cardboard and the pad is good, and the stability of the pad is further improved.
[0027] Furthermore, the width of the long plate 7 is the same as that of the pad 4. In this technical solution, after the clamping plate and the clamping wall are engaged, the long plate fits under the track shoe, and the width of the long plate is the same as that of the pad, which can maximize the area of engagement between the long plate and the bottom surface of the track shoe, making the clamping effect of the clamping plate better and effectively preventing the clamping plate from being disengaged.
[0028] Furthermore, the upper end of the short plate 6 is lower than the upper end of the support bar 2. In this technical solution, the upper end of the short plate is lower than the upper end of the support bar and the upper end surface of the pad, so as to prevent the pad from contacting the ground after deformation and causing the short plate to contact the ground, thereby avoiding damage to the structure of the cardboard.
[0029] In this specific embodiment, in order to address the problem that the existing crawler equipment walking on the bridge deck is prone to damage the bridge deck due to the structure of the crawler track, the above-mentioned scheme is achieved by setting a number of protective devices on the crawler track, and the pads of the protective devices are set in the grooves. The pads can be deformed under the action of external force so that the outer end surface of the pads is flush with the walking surface of the crawler track. Therefore, the outer end surface of the pad is squeezed and flush with the walking surface of the crawler track when it contacts the bridge deck, forming a flexible contact between the pad and the bridge deck, and increasing the contact area between the crawler track and the bridge deck, thereby greatly reducing the damage of the crawler equipment to the reinforced concrete bridge deck. Embodiment 2:
[0030] The pad 4 in the protective structure can be a resin pad. The upper end surface of the resin pad can replace the upper end surface of the support bar to contact the bridge deck (the groove width is greater than the bottom surface width of the support bar), which also increases the contact area with the bridge deck. Although it is not as large as that of elastic material, the resin material has good durability and can increase the service life of the protective device.
