Description

Technical Field

[0001] This utility model relates to the technical field of bridge erecting machines, and in particular to an adjustable transverse base for a bridge erecting machine. Background Technology

[0002] The bridge erecting machine's lateral movement system is achieved through the combined action of the main beam, crossbeam, jacks, fixed base (connected to the jacks), and anchor bolts. During operation, the fixed base is inserted into the crossbeam via a pin, connecting the jacks, base, and crossbeam as a whole. Under the action of the hydraulic pump, the main beam of the bridge erecting machine is pushed laterally. After one stroke is completed, the pin is removed, the hydraulic jack is retracted, and the base moves forward with the jacks to the next position.

[0003] The transverse base and the crossbeam of the bridge erecting machine are connected by pins. To ensure normal movement, the base and the crossbeam are not completely flush, and there is a certain gap. This causes the four pins to be misaligned when inserted, making it difficult to insert the pins. When removing the pins, the four pins are subjected to uneven force, and the gaps are not the same size, resulting in some pins being subjected to greater force and getting stuck in the hole.

[0004] Therefore, an adjustable transverse base for bridge erecting machines is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide an adjustable transverse base for a bridge erecting machine, which is based on the shortcomings of the prior art. The transverse base consists of a base body, a support, guide wheels, adjusting bolts, and a transverse jack. The gap between the base body and the upper crossbeam of the support leg is adjusted by adjusting the adjusting bolts to ensure that the holes are aligned and the pin can be inserted smoothly.

[0006] The objective of this utility model is achieved through the following technical solution: An adjustable transverse base for a bridge erecting machine is provided. Two transverse bases are arranged opposite each other. Each transverse base includes a base body, a bracket, a guide wheel, an adjusting bolt, and a transverse jack. The base body is installed on the top of the upper crossbeam on the support leg of the bridge erecting machine and fixed to the upper crossbeam by a pin. Each of the four corners of the bottom of the base body is provided with a bracket. Each bracket is provided with a guide wheel and an adjusting bolt. The transverse jack is installed on the base body.

[0007] The bottom of the horizontal side plate of the base body extends to a certain distance below the top of the upper crossbeam and is provided with a limiting mechanism.

[0008] The limiting mechanism includes an inner horizontal plate and an inner horizontal plate connected together. The inner horizontal plate and the inner horizontal plate are connected by a reinforcing plate. An outer horizontal plate is provided on the outer side of the bottom of the horizontal side plate of the base body. The outer horizontal plate and the inner horizontal plate are connected by bolts.

[0009] The bracket consists of two horizontal plates and a vertical plate arranged opposite each other. The vertical plate is connected to the horizontal plate. The guide wheel is arranged in the space formed by the vertical plate and the horizontal plate. The adjusting bolt includes an adjusting nut and an adjusting screw. The vertical plate has an adjusting screw through hole. The adjusting nut is provided at the position of the adjusting screw through hole on the vertical plate. The adjusting screw passes through the adjusting nut and the adjusting screw through hole in sequence and contacts the top of the upper crossbeam.

[0010] The base plate of the main body is provided with a sliding mechanism, which consists of a bottom moving plate and limiting plates on both sides of the bottom moving plate. The top of the upper crossbeam is provided with a guide rail, which is a top fixed plate. The bottom moving plate slides laterally along the top fixed plate.

[0011] The telescopic rod of the horizontal jack is connected to the base body, the cylinder is connected to the movable fixing device, and the movable fixing device is fixed to the upper crossbeam.

[0012] The advantages of this utility model are: (1) Convenient and fast. It takes 1 hour to move longitudinally for one stroke. After the device is installed, the time for moving transversely for one stroke is shortened to 20 minutes. Each span of steel beam needs to be moved 72m (72 strokes), saving a total of 48 hours. The entire bridge can save 40 days of construction time and 200 manpower per month. (2) Uneven force on the pin will cause it to get stuck in the hole and cannot be removed. The pin can only be cut and cannot be reused. After the modification, the material can be saved greatly. Attached Figure Description

Detailed Implementation

[0014] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art: Example: Figures 1-6 As shown, this embodiment relates to an adjustable transverse base for a bridge erecting machine. Two transverse bases are arranged opposite each other and connected to each other. The transverse base is used to support the main beam. The transverse base mainly includes a base body 10, a bracket 20, a guide wheel 30, an adjusting bolt 40, and a transverse jack 50. The base body 10 is installed on the top of the upper crossbeam 60 of the outriggers (outrigger 2 and outrigger 3) of the bridge erecting machine and fixed to the upper crossbeam 60 by a pin. A bracket 20 is provided at each of the four corners of the bottom of the base body 10. Each bracket 20 is provided with a guide wheel 30 and an adjusting bolt 40. The transverse jack 50 is installed on the base body 10. The bracket 20 consists of two horizontal plates 201 and a vertical plate 202 arranged opposite to each other. The vertical plate 202 is connected to the horizontal plate 201. The guide wheel 30 is set in the space formed by the vertical plate 202 and the horizontal plate 201 and plays a guiding role. The adjusting bolt 40 includes an adjusting nut 401 and an adjusting screw 402. The internal thread of the adjusting nut 401 and the external thread of the adjusting screw 402 are engaged. The vertical plate 202 has an adjusting screw through hole. The adjusting nut 401 is provided at the position of the adjusting screw through hole on the vertical plate 202. The adjusting screw 402 passes through the adjusting nut 401 and the adjusting screw through hole in sequence and contacts the top of the upper crossbeam 60. The gap between the base body 10 and the upper crossbeam 60 is adjusted by adjusting the adjusting bolt 40 to ensure that the hole positions (the pin holes of the base body 10 and the upper crossbeam 60) are aligned and the pin can be inserted smoothly.

[0015] like Figures 1-6As shown, the base plate of the main body 10 is provided with a sliding mechanism 70. The sliding mechanism 70 consists of a bottom moving plate 701 and limiting plates 702 on both sides of the bottom moving plate 701. The top of the upper crossbeam 60 is provided with a guide rail 80, which is a top fixed plate. The bottom moving plate 701 slides laterally along the top fixed plate. The telescopic rod of the transverse jack 50 is connected to the main body 10, and the cylinder is connected to the movable fixing device 90. The movable fixing device 90 is fixed to the upper crossbeam 60. In this embodiment, the movable fixing device 90 is also a base structure, and the movable fixing device 90 can move laterally. The movable fixing device 90 can also be fixed to the upper crossbeam 60 by a pin (or bolt). During the jacking process, the transverse jack 50 is in a retracted state, and the movable fixing device 90 is fixed to the upper crossbeam 60 (the base body 10 is not fixed to the upper crossbeam 60). The transverse jack 50 drives the base body 10 to move laterally. During the resetting process, the transverse jack 50 is in an extended state, and the base body 10 is fixed to the upper crossbeam 60 (the movable fixing device 90 is not fixed to the upper crossbeam 60). The transverse jack 50 drives the movable fixing device 90 to move laterally.

[0016] like Figures 1-4 As shown, the bottom of the transverse side plate of the base body 10 extends to a certain distance below the top of the upper crossbeam 60 and is provided with a limiting mechanism 100. The limiting mechanism 100 includes an inner transverse vertical plate 1001 and an inner horizontal plate 1002 connected to each other. The inner transverse vertical plate 1001 and the inner horizontal plate 1002 are connected by a reinforcing plate 1003. An outer transverse vertical plate 1004 is provided on the outer side of the bottom of the transverse side plate of the base body 10. The outer transverse vertical plate 1004 is connected to the inner transverse vertical plate 1001 by bolts. The limiting mechanism 100 can prevent the base body 10 from detaching from the upper crossbeam 60.

[0017] The beneficial technical effects of this embodiment are as follows: (1) Convenient and fast. It takes 1 hour to move longitudinally for one stroke. After the device is installed, the time for moving transversely for one stroke is shortened to 20 minutes. Each span of steel beam needs to be moved 72m (72 strokes), saving a total of 48 hours. The entire bridge can save 40 days of construction time and 200 manpower per month. (2) Uneven force on the pin will cause it to get stuck in the hole and cannot be removed. The pin can only be cut and cannot be reused. After the modification, the material can be saved greatly.
