Embodiment 1

[0047] Embodiment 1: a kind of as figure 1 The device shown is used in the preparation process of prestressed steel cylinder concrete pipes to realize the uniform feeding of automatic vibration-free self-compacting concrete. This device is aimed at the current preparation process of prestressed steel cylinder concrete pipes. , but there are technical difficulties in the vibrating rod penetrating into the pipe mold gap, and the cost is high when using self-compacting concrete, and the self-compacting concrete must also consider the problem of uniform feeding. The existing feeding mechanism only uses the conical cover to disperse the concrete, relying on the concrete The self-weight falls naturally, and the reliability of the uniformity of the fall is not strong. This embodiment is designed to solve this problem.

[0048] One implementation of the device looks like figure 1 As shown, it can be seen that it includes two main components: an outer cone housing assembly 1 and an in...

Embodiment 2

[0056]In the application of this embodiment, the device is hoisted directly above the mold barrel by hoisting equipment, and then lowered down to connect with the inner and outer barrels of the mold respectively, that is, the bottom of the outer frame is supported on the upper edge of the outer mold barrel, and the base is supported on the inner mold The upper edge of the tube. There are converging chamfers 19 on the periphery of the base 11, which can be centered with the inner mold barrel and drop down, and then the annular seat 18 is sleeved on the upper side of the outer mold barrel.

[0057] A pressure sensor is arranged below the annular seat 18, the inner cone cover body assembly 2 falls first, and the outer cone cover body assembly 1 falls behind, and when the pressure sensor at the bottom of the outer cone cover body assembly 1 has a pressure signal, the pressure signal is sent to The signal input terminal of the controller is controlled by the controller to drive the...

Embodiment 3

[0062] Embodiment 3: Another vibration-free self-compacting uniform feeding device for prestressed steel cylinder concrete pipes, such as Figure 9 shown (or refer to Figure 8 ), the two main components of the device are the outer cone cover assembly 1 and the inner cone cover assembly 2. from Figure 9 It can be seen that the outer cone housing assembly 1 and the inner cone housing assembly 2 are independent of each other, but are connected together through a central fixed shaft. Different from Embodiment 1, the drive motor 3 of this embodiment drives the outer cover to rotate at a uniform speed.

[0063] Figure 9 It can be seen from the figure that the outer cone cover assembly 1 includes an outer frame 4 and an inner outer cover body 5, both of which are fixed together, the outer cover body includes an upper cylindrical section and a lower conical section, the upper end of the outer cover body is an inlet, and the lower end is an outlet , the outer cover body is fixed...

Abstract

The invention discloses an automatic vibration-free self-compacting uniform blanking device for a prestressed concrete cylinder pipe, which mainly comprises an outer conical cover body assembly and an inner conical cover body assembly, the outer conical cover body assembly comprises an upper cylindrical section and a lower conical section, the inner conical cover body assembly is a cone, and the outer conical cover body assembly comprises an upper cylindrical section and a lower conical section. The outer cone cover body assembly and the inner cone cover body assembly are sleeved together and are connected through the middle shaft. After sleeving, a conical cavity exists between the rotating body and the cone, one of the rotating body and the cone is driven by a driving motor to rotate, spiral pushing plates are evenly distributed on the inner wall, located on one side of the conical cavity, of the rotating body, the width of the adjacent spiral pushing plates at the cone top is smaller than that of the cone bottom, and the height of each spiral pushing plate at the cone top is larger than that of the cone bottom. According to the application of the concrete blanking device, concrete blanking distribution is more uniform, and some embodiments adopt an automatic compaction function, so that the concrete blanking device can be suitable for ordinary concrete and self-compacting concrete.

Description

technical field [0001] The invention belongs to the technical field of prestressed steel cylinder concrete pipe (PCCP) construction equipment, and in particular relates to a vibration-free, self-compacting and uniform feeder for automatically implementing prestressed steel cylinder concrete pipes. Background technique [0002] Prestressed concrete cylinder pipe (PCCP for short) is composed of protective layer mortar, prestressed steel wire, concrete tube core and anti-seepage steel bar. The prestressed steel wire is the main carrier of internal pressure, and the concrete tube core is the main carrier of external load. It is a high-strength concrete tube core with a steel cylinder wound with prestressed steel wire, sprayed with a cement mortar protective layer, using a steel socket, and welded together with the steel cylinder. It is made of steel plate, concrete, high-strength steel wire and cement mortar. composed of composite structures. It has the recognized characterist...
