Description

Technical Field

[0001] The utility model relates to the technical field of road and bridge engineering, in particular to a connection and locking device for bridge templates. Background Art

[0002] Road and bridge engineering originally refers to a series of work including survey, design, construction, maintenance, and management of roads and bridges. It involves not only the construction of the main structures of roads and bridges, but also the construction of supporting facilities and ancillary projects related to roads and bridges.

[0003] However, the existing connection and locking device of bridge templates has the following disadvantages:

[0004] (1) The existing bridge template connection locking device has a weak function of quick adaptation and clamping. When in use, the existing technology usually requires workers to clamp the bridge template to fit the bridge template, which is convenient for pouring concrete. Since the workers clamp the template manually, not only is the clamping force low, but the work efficiency is also slow;

[0005] (2) The existing connection and locking device of the bridge template has a weak function of adapting to the working environment. When in use, due to the different terrain heights during the installation of the bridge, the angle of the template or clamping device needs to be fine-tuned according to the terrain environment. The existing technology has certain limitations. Utility Model Content

[0006] The purpose of the utility model is to provide a connection and locking device for bridge templates to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a connection and locking device for a bridge formwork, comprising a first clamping frame, the inner wall of the first clamping frame being slidably connected to the second clamping frame, the first clamping frame and the second clamping frame being fixedly connected to a connecting plate on their sides, the inner wall of the connecting plate being provided with a first threaded rod, a first motor being installed on one side of the connecting plate, the first threaded rod being located at the output end of the first motor, the surfaces of the first clamping frame and the second clamping frame being fixedly connected to a bearing, the inner wall of the bearing being provided with a fixing plate, the top of the fixing plate being provided with a second motor, the output end of the second motor being provided with a second threaded rod, the surface of the fixing plate being fixedly connected to a card plate, and a card block being fixedly connected to one side of the card plate.

[0008] Optionally, the inner walls of the first clamping frame and the second clamping frame are provided with fixing grooves, and the inner walls of the fixing grooves are fixedly connected with anti-slip pads. By installing the anti-slip pads, the anti-slip pads can be used to prevent the device from slipping when clamping the bridge formwork.

[0009] Optionally, a thread groove is provided on the surface of the fixing plate, and the thread groove is located on the surface of the second threaded rod.

[0010] Optionally, a connecting groove is provided on one side of the first clamping frame and the second clamping frame, and the connecting groove is located on one side of the clamping block, and the connecting groove is connected to the clamping block.

[0011] Optionally, the first clamping frame is smaller than the width of the second clamping frame, and the first clamping frame fits the second clamping frame.

[0012] Optionally, a limit rod is installed between the first clamping frame and the second clamping frame, and the limit rod is slidably connected to the first clamping frame and the second clamping frame. The installation of the limit rod is used to ensure the stability of the first clamping frame and the second clamping frame when they move up and down.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The existing connection and locking device of the bridge template is provided with a first clamping frame, a second clamping frame, a connecting plate, a first threaded rod and a first motor. When in use, the first threaded rod can be driven to rotate by an external power supply of the first motor, and the rotation of the first threaded rod can drive the first clamping frame and the second clamping frame to move to the opposite side. The bridge templates placed inside the first clamping frame and the second clamping frame can be clamped and adapted according to the bridge template, and due to the installation of the first motor, the clamping force is increased and the working efficiency is improved, thereby achieving the effect of improving the clamping efficiency.

[0015] 2. The existing connection and locking device of the bridge formwork is provided with a bearing, a fixed plate, a second motor, a second threaded rod, a clamping plate and a clamping block. When in use, due to the uneven terrain, gravity will drive the fixed plate to deviate to the lower side inside the bearing, so that the device maintains a stable horizontal line when clamping. The installation of the clamping plate and the clamping block ensures that the fixed plate is limited when rotated to a certain angle to avoid excessive rotation. The external power supply of the second motor can drive the device to move up and down to the opposite side, and adapt according to the height of the formwork, so as to achieve the effect of facilitating fine-tuning the angle to adapt to different installation environments.
