Description

Technical Field

[0001] The present application relates to the technical field of bridge construction, and in particular to a connection device for upper and lower supports of a spherical steel support. Background Art

[0002] Spherical steel bearings are important supporting devices in railway bridges and elevated track structures. They are mainly used to bear the vertical load of the bridge while allowing a certain amount of horizontal displacement and rotation to adapt to the deformation of the bridge under temperature changes, loads and other external factors.

[0003] After the spherical steel bearing is installed and manufactured, the upper and lower bearings of the spherical steel bearing need to be temporarily connected and fixed to prevent the upper bearing from shaking on the lower bearing during transportation and causing damage to the equipment, thereby ensuring the safety and integrity of the spherical steel bearing during transportation.

[0004] Currently, the upper and lower supports of spherical steel bearings are temporarily connected and fixed by bolts through holes reserved in the upper and lower supports to prevent shaking during transportation. However, due to the large number of bolts required for installation and removal, it takes a long time. At the same time, the small space between the upper and lower supports and the limited construction space on the bridge piers lead to certain restrictions in the bolt removal process, which is inconvenient for construction workers and affects construction efficiency.

[0037] After the spherical steel bearing is installed and manufactured, the upper and lower bearings of the spherical steel bearing need to be temporarily connected and fixed to prevent the upper bearing from shaking on the lower bearing during transportation and causing damage to the equipment, thereby ensuring the safety and integrity of the spherical steel bearing during transportation.

[0038] Currently, the upper and lower supports of spherical steel bearings are temporarily connected and fixed by bolts, usually through holes reserved in the upper and lower supports to prevent shaking during transportation. However, due to the large number of bolts required for installation and removal, it takes a long time. At the same time, the small space between the upper and lower supports and the limited construction space on the bridge piers lead to certain restrictions in the bolt removal process, making it inconvenient for construction workers and affecting construction efficiency.

[0039] In response to the above problems, an embodiment of the present application provides a connection device for the upper and lower supports of a spherical steel support, which can temporarily connect and fix the upper and lower supports of the spherical steel support, and is convenient for installation and disassembly, thereby ensuring the construction efficiency of the spherical steel support.

[0047] See also Figure 1-6 A connecting device for the upper and lower supports of a spherical steel support, which is installed on the spherical steel support 6 and is used to connect and fix the upper and lower supports of the spherical steel support 6. The connecting device includes: a first connecting block 1, a second connecting block 2, an upper support pin 3, a lower support pin 4 and a connecting pin 5.

[0048] Specifically, the upper support pin 3, lower support pin 4, and connecting pin 5 are all stainless steel spring ball pins, each equipped with a pin handle 301. The length of each pin is determined based on the actual insertion depth to ensure connection stability after insertion.

[0049] In this embodiment, by using a stainless steel spring ball head latch, the operator can quickly and easily connect and disassemble. At the same time, the design of the latch handle 301 makes the insertion and removal of the latch more convenient, and can quickly complete the disassembly work in a small environment, ensuring work efficiency.

[0050] The first connecting block 1 is provided with a connecting slot 101 for clamping the first connecting block 1, and upper connecting through holes 102 are provided on two side panels of the connecting slot 101;

[0051] The first connecting block 1 is provided with an upper connecting plate 103 for connecting and fixing the second connecting block 2, and a first fixing through hole 104 is provided on the upper connecting plate 103;

[0052] Both sides of the upper support are provided with first support through holes 601 for installing the upper support pin 3. The upper support pin 3 passes through the upper connecting through hole 102 and the first support through hole 601 in sequence to connect and fix the first connecting block 1 and the upper support.

[0053] In this embodiment, the first connection block 1 can be fixedly mounted on the upper support by using the upper support pin 3 to connect and fix the first connection block 1 and the upper support.

[0054] The second connecting block 2 is provided with a lower connecting through hole 201 for fixedly connecting to the lower support; the second connecting block 2 is provided with a second fixing through hole 202 for fixedly connecting to the first connecting block 1;

[0055] Second support through holes 602 for installing lower support pins 4 are provided on both sides of the lower support. The lower support pins 4 pass through the second support through holes 602 and the lower connecting through holes 201 in sequence to connect and fix the second connecting block 2 and the lower support.

[0056] In this embodiment, the second connecting block 2 is fixedly mounted on the lower support by connecting and fixing the second connecting block 2 to the lower support using the lower support pin 4. The connecting pin 5 passes through the first fixing through-hole 104 and the second fixing through-hole 202 in sequence, connecting and fixing the first connecting block 1 and the second connecting block 2, thereby connecting and fixing the upper support and the lower support.

[0057] In this embodiment, by installing two sets of connecting devices of the present application on both sides of the spherical steel support 6, the upper support and the lower support of the spherical steel support 6 can be effectively connected and fixed, effectively preventing the upper support from shaking on the lower support during transportation and causing damage to the equipment. At the same time, by using the connection and fixing method of the pin, it can be convenient for installation and disassembly, thereby ensuring the construction efficiency of the spherical steel support 6.

[0058] Specifically, a first groove 1011 is provided on the inner wall of the bottom of the connecting slot 101 , and a rubber pad is provided inside the first groove 1011 .

[0059] In this embodiment, by providing a rubber pad in the connecting slot 101, the contact between the connecting slot 101 and the upper support can be made closer, thereby increasing the installation stability of the first connecting block 1. At the same time, the upper support can be prevented from being scratched by the connecting slot 101, thereby protecting the integrity of the equipment.

[0060] Specifically, the first connecting block 1 and the second connecting block 2 are integrally formed and made of aluminum alloy.

[0061] In this embodiment, the aluminum alloy formed in one piece can provide sufficient structural strength while maintaining a relatively light weight, can withstand a certain load, and ensure the stability of the installation connection.

[0062] The technical solution in the embodiment of the present application includes the following beneficial effects: the present application can effectively connect and fix the upper support and the lower support of the spherical steel support 6 by arranging an installation and connection device on the spherical steel support 6, effectively preventing the upper support from shaking on the lower support during transportation and causing damage to the equipment. At the same time, by using a connection and fixing method with a pin, it can facilitate installation and disassembly, thereby ensuring the construction efficiency of the spherical steel support 6.
