[0015] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0016] The technical solution specifically implemented by the present utility model is as follows:

[0017] As Figure 1 and Figure 2 shown, a movable choke and kill manifold includes a choke and kill manifold body 1. The choke and kill manifold body 1 is fixedly installed on a movable plate 2. A bottom plate 3 is arranged below the movable plate 2. A telescopic support assembly 4 is connected between the movable plate 2 and the bottom plate 3. A receiving groove 5 is formed at the bottom of the bottom plate 3. A lifting wheel seat 6 is movably arranged in the receiving groove 5. A roller 7 is arranged on the bottom surface of the lifting wheel seat 6. A jacking mechanism 8 for ejecting the roller 7 out of the receiving groove 5 in the shortest state of the telescopic support assembly 4 is arranged on the lifting wheel seat 6. The jacking mechanism 8 can abut against the movable plate 2.

[0018] The above-mentioned ejection mechanism 8 includes a through groove 82 and an ejector pin 81. The through groove 82 is provided on the bottom plate 3, and the through groove 82 communicates with the receiving groove 5. The ejector pin 81 is slidably arranged in the through groove 82. The lower end of the ejector pin 81 is fixedly connected to the lifting wheel seat 6. The upper end of the ejector pin 81 extends between the movable plate 2 and the bottom plate 3, and the upper end of the ejector pin 81 can abut against the movable plate 2. Specifically, during the movement, the movable plate 2 is attached to the bottom plate 3. The movable plate 2 ejects the lifting wheel seat 6 in the receiving groove 5 of the bottom plate 3 through the ejector pin 81, so that the roller 7 of the lifting wheel seat 6 protrudes from the bottom surface of the bottom plate 3, thereby facilitating the movement of the throttle kill manifold body 1.

[0019] The above-mentioned telescopic support assembly 4 includes a hydraulic cylinder 41 and a telescopic column 42. The hydraulic cylinder 41 is arranged in the bottom plate 3, the telescopic column 42 is arranged on the top of the hydraulic cylinder 41, and the top of the telescopic column 42 is connected to the movable plate 2. Specifically, during the process of raising the throttle kill manifold body 1, the hydraulic cylinder 41 is started, and the throttle kill manifold body 1 on the movable plate 2 is driven to move upward through the telescopic column 42.

[0020] The depth of the above-mentioned receiving groove 5 is adapted to the sum of the heights of the lifting wheel seat 6 and the roller 7. Specifically, it is beneficial for the receiving groove 5 to completely retract the lifting wheel seat 6 and the roller 7, so that the bottom plate 3 is in contact with the ground, fixing the entire device in the installation position and improving the stability.

[0021] The number of the above-mentioned telescopic support assemblies 4 is four groups, and the four groups of telescopic support assemblies 4 are respectively arranged at the four corners of the bottom plate 3. Specifically, it is beneficial to improve the stability during the process of lifting the throttle kill manifold body 1.

[0022] During use, the throttle kill manifold body 1 is installed on the movable plate 2. When the telescopic support assembly 4 between the movable plate 2 and the bottom plate 3 is in the shortest state, the movable plate 2 is attached to the bottom plate 3. The movable plate 2 ejects the lifting wheel seat 6 in the bottom plate 3 through the ejector pin 81 of the ejection mechanism 8, so that the roller 7 of the lifting wheel seat 6 protrudes from the bottom surface of the bottom plate 3, thereby facilitating the movement of the throttle kill manifold body 1 to the position where it needs to be installed. Then, the throttle kill manifold body 1 on the movable plate 2 is lifted by the telescopic support assembly 4 to adjust the height of the throttle kill manifold body 1, so as to facilitate the throttle kill manifold body 1 to adapt to installation positions at different heights. When the movable plate 2 moves upward, the movable plate 2 is separated from the ejector pin 81 of the ejection mechanism 8. Due to the self-weight of the entire device, the lifting wheel seat 6 and the roller 7 are completely retracted into the receiving groove 5 of the bottom plate 3, so that the bottom plate 3 is in contact with the ground, fixing the entire device in the installation position and improving the stability.

[0023] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
