It is a mobile crane equipped with special attachments for assembling and pushing prefabricated bridge components, splicing individual steel bridge frames one by one to form a complete bridge.

[0004] In the prior art, since the bridge decks laid inside the steel bridge frame are usually provided with anti-skid grooves on their upper sides to prevent the wheels from slipping, when it snows, some snow will enter the grooves of the anti-skid grooves and form ice after the snow melts, causing the wheels to slip, making it very easy for the moving wheels to get into a traffic accident. Summary of the invention

[0005] The purpose of the utility model is to provide a combined bridge frame that is convenient for transporting materials, which can break the ice layer on the surface of the bridge deck when the wheels pass through the bridge deck, thereby avoiding the wheels from slipping when passing through the bridge deck. The broken ice layer will increase the friction coefficient of the bridge deck surface, so that the wheels can roll more smoothly over the bridge deck, thereby reducing the occurrence of traffic accidents, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a combined bridge frame for facilitating material transportation, comprising a steel bridge frame, an ice-breaking component is provided on the lower side of the steel bridge frame, the ice-breaking component comprises two storage grooves provided on the lower side of the steel bridge frame, and two unlocking components are provided inside the steel bridge frame;

[0009] Preferably, the locking assembly comprises two movable grooves provided on both sides of the bridge plate, and the interiors of the two movable grooves are both slidably connected to limit plates, and the limit plates are in a "T" shape.

[0010] Preferably, two second return springs are fixedly connected to one side of the opposite surfaces of the two limit plates, and one end of the opposite surfaces of the two second return springs is respectively fixedly connected to the adjacent side inside the two moving grooves.

[0011] Preferably, guide grooves are provided on both sides of the storage groove, the two movable grooves correspond to the positions of the two guide grooves, and the two limit plates are slidably connected in the two guide grooves respectively.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. After the bridge deck is pressed, the pillars are exposed from the through holes and break the ice on the bridge deck surface.

[0026] 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.

[0027] The utility model provides a technical solution:

[0028] See also Figures 1 to 5A combined bridge frame for material transportation includes a steel bridge frame 1, an ice-breaking component 2 is provided on the lower side of the steel bridge frame 1, the ice-breaking component 2 includes two storage grooves 21 provided on the lower side of the steel bridge frame 1, and two unlocking components 3 are provided inside the steel bridge frame 1;

[0029] There are two bridge plates 22 slidably connected inside the two receiving grooves 21, and a number of columns 23 are fixedly connected to the inner bottom end of the receiving grooves 21. The outer sides of the columns 23 are sleeved with first return springs 24. A number of first movable grooves 25 are opened at the bottom of the bridge plate 22, and the number of columns 23 are respectively slidably connected inside the number of first movable grooves 25. The top of the first return spring 24 and the top of the first movable groove 25 overlap each other. A number of through holes 26 are opened at the top of the bridge plate 22, and the number of through holes 26 are respectively connected to the number of first movable grooves 25, and the upper parts of the number of columns 23 are respectively slidably connected in the number of through holes 26. Two locking components 27 are provided on both sides of the two bridge plates 22 and the two sides inside the steel bridge frame 1.

[0030] The cross-sectional diameter of the inner cavity of the first movable groove 25 is the same as the cross-sectional diameter of the lower half of the column 23 , and the cross-sectional diameter of the inner cavity of the through hole 26 is the same as the cross-sectional diameter of the upper half of the column 23 .

[0031] The locking assembly 27 includes two moving grooves 271 formed on both sides of the bridge plate 22 . The interiors of the two moving grooves 271 are both slidably connected with a limiting plate 272 , and the limiting plate 272 is in a “T” shape.

[0032] Two second return springs 273 are fixedly connected to one side of the opposite surfaces of the two limit plates 272 , and one end of the opposite surfaces of the two second return springs 273 is fixedly connected to one side close to the inside of the two moving grooves 271 .

[0033] Guide grooves 274 are provided on both sides of the receiving groove 21 . The two movable grooves 271 correspond to the positions of the two guide grooves 274 . The two limiting plates 272 are slidably connected in the two guide grooves 274 , respectively.

[0034] By adopting the above technical solution, first, when a vehicle transporting materials passes through the steel bridge frame 1 and the surface of the bridge deck 22 is frozen, the vehicle will directly roll over the bridge deck 22 inside the storage groove 21, and the bridge deck 22 will move downward in the storage groove 21 inside the steel bridge frame 1 after being subjected to downward pressure. Because the column 23 inside the storage groove 21 corresponds to the position of the first movable groove 25 below the bridge deck 22, the column 23 moves inside the first movable groove 25. At the same time, the first movable groove 25 and the through hole 2 6 is connected, and the through hole 26 passes through the upper side of the bridge plate 22, so that the lower side of the bridge plate 22 is completely in contact with the lower side of the inner side of the receiving groove 21, and the column 23 will pass through the through hole 26 and be exposed from above the bridge plate 22. In the process of the column 23 being exposed above the bridge plate 22 through the through hole 26, the column 23 will lift the ice layer above the bridge plate 22, and after the vehicle passes, the ice layer crushed by the column 23 will be further crushed, and the crushed ice will increase the friction coefficient of the upper side of the bridge plate 22.

[0035] After the vehicle leaves, the first return spring 24 on the outer side of the column 23 will quickly return the bridge plate 22. During the movement of the bridge plate 22 in the storage slot 21, the second return springs 273 in the movable slots 271 on both sides of the bridge plate 22 will always push the limit plate 272. After the limit plate 272 is pushed out of the movable slot 271, it will enter the guide slots 274 on both sides of the storage slot 21. When the bridge plate 22 moves up and down in the storage slot 21, the limit plates 272 on both sides will also slide in the two guide slots 274. Because the upper side of the guide groove 274 is not connected to the outside world, the limit plate 272 can only move inside the guide groove 274. As the bridge plate 22 is repeatedly pressed, the column 23 is repeatedly exposed from the inside of the through hole 26, so that the ice layer above the bridge plate 22 is repeatedly squeezed, and the ice layer is crushed and then crushed by the wheels, which prevents the wheels from slipping when passing through the bridge plate 22. The crushed ice layer will increase the friction coefficient of the surface of the bridge plate 22, so that the wheels can roll more smoothly over the bridge plate 22, thereby reducing the occurrence of traffic accidents.

[0036] Specifically, Figure 4 and Figure 5 As shown, the unlocking component 3 includes a gear 31 rotatably connected to the inside of the steel bridge frame 1, two racks 32 are meshed on the outer side of the gear 31, and the moving directions of the two racks 32 are opposite, and one end of the opposite surfaces of the two gears 31 are fixedly connected with a rotating rod 35, and the two rotating rods 35 are both located between the two bridge plates 22.

[0037] A push block 33 is fixedly connected to the side of the two racks 32 that is away from each other. An inclined surface is provided on the side of the two push blocks 33 that is close to the limiting plate 272 , and the inclined surface faces away from the racks 32 .

[0038] Four second movable grooves 34 are formed inside the side wall of the steel bridge frame 1 , and four push blocks 33 are slidably connected in the four second movable grooves 34 , respectively. The push blocks 33 push the limit plate 272 when they are close to the limit plate 272 .

[0039] By adopting the above technical solution, when the first return spring 24 is damaged after long-term use, it needs to be maintained to ensure the normal ice-breaking function. At this time, the rotating rod can be rotated to drive the internal gear 31 of the steel bridge frame 1 to rotate. Because the two racks 32 on the outside of the gear 31 move in opposite directions and are both engaged with the gear 31, when the gear 31 rotates, the two racks 32 will respectively drive the two push blocks 33 to move in opposite directions. As the two push blocks 33 move inside the two second movable grooves 34, the inclined surface of the push block 33 will gradually push the limit block. When the push block 33 reaches the other side of the second movable groove 34, the widest part of the push block 33 will be in contact with the limit block. The limit plate 272 contacts and pushes the limit plate 272 out of the guide groove 274. After the limit plate 272 is completely separated from the guide groove 274, the first return spring 24 will push the bridge plate 22 upward, so that the bridge plate 22 can gradually separate from the receiving groove 21, and then the first return spring 24 inside the receiving groove 21 can be maintained or replaced. Since the limit plate 272 is restricted in the guide groove 274, the bridge plate 22 will also be restricted in the receiving groove 21. After the limit plate 272 is pushed out of the guide groove 274, the bridge plate 22 will be able to separate from the receiving groove 21, so as to facilitate the subsequent maintenance or replacement of the first return spring 24 and other structures.

[0040] Working principle: When the bridge deck 22 is frozen, the vehicle will directly roll over the bridge deck 22. The bridge deck 22 will move downward in the receiving groove 21 under pressure. Since the first movable groove 25 is connected with the through hole 26, and the through hole 26 passes through the upper side of the bridge deck 22, the lower side of the bridge deck 22 is completely in contact with the lower side of the receiving groove 21. Then, the column 23 will pass through the through hole 26 and be exposed from the upper side of the bridge deck 22. The ice layer above the bridge deck 22 will be lifted. After the vehicle passes by, the ice layer crushed by the column 23 will be further rolled.

[0041] After the vehicle leaves, the first return spring 24 on the outside of the column 23 will quickly return the bridge plate 22, and the second return spring 273 inside the moving groove 271 on both sides of the bridge plate 22 will always push the limit plate 272 and enter the guide groove 274. When the bridge plate 22 moves up and down inside the storage groove 21, the limit plates 272 on both sides will also slide inside the two guide grooves 274. When the rotating rod is rotated to drive the internal gear 31 of the steel bridge frame 1 to rotate, the two racks 32 will respectively drive the two push blocks 33 to move in opposite directions, and the inclined surface of the push block 33 will also gradually push the limit block. After the widest part of the push block 33 is in contact with the limit plate 272, the limit plate 272 is pushed out of the guide groove 274. At this time, the first return spring 24 will push the bridge plate 22 upward, so that the bridge plate 22 can gradually leave the storage groove 21, and then the first return spring 24 inside the storage groove 21 can be maintained or replaced.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
