[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments (for the convenience of description and understanding, the following is a schematic diagram of the present invention). Figure 1 Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.
[0017] See also Figure 1-4The utility model provides a technical solution: a detachable and cleanable tunnel template trolley concrete pouring device, comprising a trolley template 1, a trolley template pouring hole 6 is arranged on the trolley template 1, a pump pipe joint 7 is arranged below the trolley template 1, a blocking plate 2 is arranged on one side of the lower end of the trolley template 1, a blocking plate pouring hole 4 is arranged on the blocking plate 2, one side of the blocking plate 2 is connected to the telescopic end of the hydraulic cylinder 3, and the blocking plate 2 is located between the trolley template 1 and the pump pipe joint 7. When pouring concrete, the hydraulic cylinder 3 pushes the blocking plate 2 to move between the pump pipe joint 7 and the trolley template 1, so that the blocking plate pouring hole 4 on the blocking plate coincides with the central axis of the trolley template pouring hole 6 and the pump pipe joint 7. When blocking is required, the blocking plate 2 is continued to be pushed to move so that the blocking plate 2 blocks the trolley template pouring hole 6;
[0018] The upper end of the pump pipe joint 7 is fixedly connected to the flange plate 8, and a swing ear plate 10 is symmetrically fixed to the lower end of the outer side surface of the flange plate 8. One end of the swing ear plate 10 is located between the two fixed ear plates 11. A swing pin 9 passes between the swing ear plate 10 and the fixed ear plate 11. The fixed ear plate 11 is fixed to the lower end of the trolley template 1. When it is necessary to clean the concrete around the sealing plate 2, remove the swing pin 9 on one side to rotate the pump pipe joint 7 to expose the concrete filled in the gap for the convenience of workers to clean.
[0019] Furthermore, in order to improve the support stability of the pump pipe joint 7 , the number of the swing ear plates 10 is four, and the four swing ear plates 10 are symmetrically arranged in pairs at the lower end of the flange plate 8 .
[0020] Furthermore, in order to ensure that the moving direction of the blocking plate 2 does not deviate, guide plates 5 are symmetrically arranged at the lower end of the trolley template 1. The guide plates 5 are located on both sides of the blocking plate 2, and the distance between the two relatively arranged guide plates 5 is greater than the width dimension of the blocking plate 2.
[0021] Furthermore, the number of the guide plates 5 is four, and the four guide plates 5 are symmetrically arranged in pairs on both sides of the blocking plate 2, and one pair of the guide plates 5 is located on both sides of the casting hole 6 of the trolley template to facilitate the movement of the blocking plate 2 into place.
[0022] During use: before the template trolley pours concrete, the blocking plate 2 is in a blocked state. The hydraulic cylinder is operated to contract through the hydraulic and electrical control system to pull the blocking plate 2 to move, so that the blocking plate casting hole 4 coincides with the trolley template casting hole 6, and then the concrete pouring is carried out. After the pouring operation is completed, the swing pin shaft 9 on one side is removed. At this time, the pump pipe joint 7 rotates to expose the concrete around the blocking plate 2. The worker cleans the concrete. After the cleaning is completed, the pump pipe joint 7 is reset and the swing pin shaft 9 is reinstalled.
[0023] The utility model can be conveniently operated, occupies little space when in use, is easy to operate and use; the pump pipe joint 7 can be quickly displaced, which is convenient for cleaning the concrete around the blocking plate 2, preventing the pump pipe joint 7 from being damaged, increasing the service life, and greatly improving the construction efficiency.
[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
