Description

Automatic lifting type base for distributing machine

Technical Field

The invention belongs to the technical field of auxiliary equipment of a material distributing machine, and particularly relates to an automatic lifting type base for the material distributing machine.

Background

In the construction process of a construction engineering project, when the vertical distance or the horizontal distance of concrete pouring exceeds the application range of an automobile pump (a top pump), a vehicle-mounted pump or a pull-type pump (a ground pump) is required to be matched with a distributor to carry out concrete pouring operation. Meanwhile, in order to ensure the stability of each device and avoid the influence of each device on the construction process, a ground pump and a distributing machine are generally arranged on the second floor below the construction floor, a distributing part (a transverse distributing rod for discharging concrete) of the distributing machine extends out to the upper part of the construction floor, and a feeding part (a vertical distributing pipe communicated with the distributing rod and used for conveying concrete from bottom to top) of the distributing machine is communicated with the ground pump. The concrete is conveyed into the distributing pipe through a pumping pipe connected to the ground pump, conveyed into the distributing rod through the distributing pipe and finally poured on the surface of the construction floor; the worker controls the material distribution part of the material distributor to move at the first floor below the construction floor, so that concrete pouring operation is carried out on the construction floor.

That is, as shown in fig. 1, in order to pour concrete on the X-level, the base 110 of the distributor and the ground pump 200 are installed on the X-2 level at the same time, and the distributing pipe 120 is communicated with the pumping pipe 210; and a preformed hole 300 communicated with the X-2 layer is formed in the surface of the X-1 layer, so that the distributing machine can extend out to the position, above the X layer, of the distributing rod 130.

In the construction process of the X layer, since the distribution rod cannot cast the base 110 through the position of the X layer, the preformed hole 300 is also formed on the surface of the X layer.

After the construction of the layer X is completed, the base 110 needs to be moved from the layer X-2 to the layer X-1 through the preformed holes of the layer X-1 by the elevator, so that the material distribution rod 130 is moved to above the layer X +1, and the material distribution operation is continued for the layer X + 1.

In order to allow the base 110 to pass through the prepared hole and be supported on the floor surface in the prior art, a support leg 140 extending away from the base 110 in a horizontal direction is provided at the bottom of the base 110, and the support leg 140 is detachably coupled to the base 110. When moving the base upward, the worker removes the support leg 140 so that the base 110 can pass through the prepared hole 300; after the base 110 passes through the prepared hole 300, the worker mounts the support leg 140 on the base 110 so that the base 110 can be supported on the floor surface.

The inventors found that when the susceptor 110 is moved by the lifter, there are the following construction problems:

(1) calibration is needed when the hoist is used each time, so that the central axis of a lifting arm (extending in the vertical direction, connected with the base 110 and used for driving the base 110 to lift) of the hoist coincides with the central axis of the base 110;

(2) after the support legs 140 are detached from the X-2 layer, workers need to manually convey the support legs to the X-1 layer and install the support legs;

above two construction problems all can lead to the increase of the time that the cloth machine consumed that removes to reduce cloth machine's removal efficiency.

Referring to fig. 2 to 9, the automatic lifting type base for a material distributing machine according to the present invention will be described. The automatic lifting type base for the material distribution machine comprises a vertical seat 1, a base 2 and a fixing plate 3.

The vertical seat 1 is used for supporting the distributing rod 130, and adopts an internal hollow structure, and the vertical seat 1 is provided with two external interfaces 11 which are communicated with the inner cavity and are respectively used for the pumping pipe 210 or the distributing pipe 120 to pass through, and in the embodiment, the two external interfaces 11 are respectively positioned on the side surface and the top surface of the vertical seat 1.

In the present embodiment, for convenience of description, the external interface 11 is defined to be located on the upper surface of the stand 1, and the front/rear side surface.

Tooth grooves 12 are respectively arranged on the outer walls of the left side and the right side of the vertical seat 1, and the tooth grooves 12 extend along the height direction of the vertical seat 1.

The base 2 is fixedly arranged on the bottom surface of the vertical seat 1 and used for supporting the vertical seat 1, and the base 2 adopts a cylindrical structure with a hollow interior and is suitable for passing through the preformed hole 300.

Two supporting pieces 21 which are arranged in a sliding manner along the left-right direction are arranged in the base 2, and the sliding directions of the two supporting pieces 21 are opposite; in the present embodiment, the supporting member 21 is in an elongated structure, and for convenience of description, one end of the supporting member 21 closer to the central axis of the base 2 is defined as an inner end of the supporting member 21, and correspondingly, the other end of the supporting member 21 is defined as an outer end of the supporting member 21. An elastic member 22 for contacting the base 2 and driving the support member 21 to move horizontally outward of the base 2 is connected to an inner end of the support member 21.

The inner end of the supporting piece 21 is positioned in the base 2, and the outer end of the supporting piece 21 extends out of the left/right side wall of the base 2; wherein the lower surface of the protruding portion of the support member 21 is used to support the second floor surface below the construction floor, and the upper surface of the protruding portion adopts a first inclined surface inclined downward in the direction from the inner end to the outer end. As the base 2 moves upward, the first inclined surface is used to abut against the lower edge of the prepared hole 300 to move the supporter 21 toward the base 2.

The fixing plate 3 is used for being fixedly connected to the surface of the first floor below the construction floor, and is provided with a through hole 31 penetrating along the vertical direction, and the through hole 31 is used for being communicated with the preformed hole 300 and also used for allowing the vertical seat 1 and the base 2 to pass through. In the present embodiment, the edge of the through hole 31 is outside the edge of the prepared hole 300, so that the support 21 can be protruded and moved toward the inner wall of the through hole 31 after the base 2 passes through the prepared hole 300.

Two sliding members 32 are slidably provided on the upper surface of the fixed plate 3 in the left-right direction, and the two sliding members 32 are arranged side by side in the left-right direction on both sides of the vertical base 1.

The slider 32 is rotatably provided with an engaging assembly for engaging with the gullet 12, that is, the engaging assembly can be moved into engagement with the outside of the gullet 12 as the slider 32 is moved in the left-right direction.

The fixed plate 3 is further provided with two locking pieces 33, and the two locking pieces 33 are respectively used for being connected with the two sliding pieces 32 so as to limit the movement of the sliding pieces 32; when the engaging member is engaged with the outside of the slot 12, the engaging member can be prevented from being separated from the slot 12 by restricting the movement of the slider 32 by the locking member 33.

When the lower edge of the supporting member 21 passes through the upper edge of the prepared hole 300, the elastic member 22 can drive the supporting member 21 to move outward of the base 2 until the protruding end of the supporting member 21 abuts against the sliding member 32; at this time, the locking member 33 is separated from the slider 32, and the support member 21 can push the slider 32 until the engaging assembly is separated from the slot 12.

When in use, the vertical base 1 is driven to ascend through the meshing component. When the vertical seat 1 drives the base 2 to pass through the prepared hole 300, the first inclined surface of the support 21 abuts against the lower edge of the prepared hole 300, so that the support 21 moves into the base 2. After the base 2 passes through the prepared hole 300 (the lower edge of the supporter 21 passes through the upper edge of the prepared hole 300), the elastic member 22 drives the supporter 21 to move outward into abutment with the slider 32; by disengaging the locking member 33 from the sliding member 32, the support member 21 continues to move outwardly and drives the sliding member 32 away from the base 2 so that the engagement assembly and the socket 12 are disengaged, and the bottom surface of the support member 21 can be supported on the floor surface to provide a stable supporting force for the riser 1.

Referring to fig. 2, 8 and 9, as an embodiment of the automatic lifting base for a material distributing machine according to the present invention, a limiting member 34 protruding toward the space between two sliding members 32 is disposed on adjacent side surfaces of the two sliding members 32; that is, the slider 32 abuts against the support 21 through the stopper 34.

The end surface of the protruding end of the stopper 34 is a second inclined surface adapted to abut against the first inclined surface, and as shown in fig. 9, the second inclined surface is an inclined structure inclined upward along the extending direction of the stopper 34, and when the first inclined surface and the second inclined surface contact, an interaction force for limiting the up-and-down movement of the slider 32/the support 21 is generated between the two surfaces.

The bottom surface of the stopper 34 is provided with an abutment plate 341 adapted to abut against the outer end of the stay 21, thereby preventing the support 21 from moving excessively to insert the protruding end of the stay 21 into the gap between the fixed plate 3 and the floor.

By adopting the technical scheme, the relative movement of the sliding part 32 and the supporting part 21 along the vertical direction and the excessive movement of the supporting part 21 are avoided, and the structural stability and the reliability in practical use of the device are improved.

Referring to fig. 2 to 5, as a specific embodiment of the automatic lifting base for a material distributing machine provided by the present invention, an upward extending vertical plate 23 is disposed in the base 2, and two side plate surfaces of the vertical plate 23 face the two supporting members 21 respectively; that is, both side surfaces of the standing plate 23 face to the left and right sides, respectively.

The elastic member 22 is a spring with one end fixed on the plate surface of the vertical plate 23 and the other end fixed on the inner end surface of the support member 21.

Through adopting above-mentioned technical scheme, riser 23 supports the spring of both sides simultaneously, and the spring provides driving force (elasticity) outside towards base 2 for support piece 21 is in the state of stretching out base 2 constantly, has improved the structural stability of this device.

Referring to fig. 2 to 5, as a specific embodiment of the automatic lifting base for a material distributor provided by the present invention, a central rod 24 inserted into the spring is disposed on both side plate surfaces of the vertical plate 23 to limit the spring from buckling and deforming in a direction perpendicular to its own stretching direction; specifically, when the spring undergoes buckling deformation in its own radial direction, the inner peripheral wall of the spring comes into contact with the outer peripheral wall of the central rod 24, thereby counteracting the aforementioned buckling deformation acting force.

One side of the supporting member 21 facing the vertical plate 23 is provided with an insertion groove 211 for inserting the central rod 24, and the central rod 24 is inserted into the insertion groove 211, so that the situation that the central rod 24 limits the supporting member 21 to move towards the base 2 can be avoided.

Wherein, the inserting groove 211 adopts a structure that the groove bottom gradually reduces to the opening of the notch, and one end of the central rod 24 inserted into the inserting groove 211 is provided with a clamping ring 241 which radially extends along the self and is used for being abutted against the notch.

By adopting the above technical scheme, the central rod 24 can avoid the buckling deformation of the spring; the combined structure of the central rod 24 and the inserting groove 211 can prevent the central rod 24 from limiting the movement of the support piece 21, so that the structural stability and the reliability of the device in actual use are improved; the snap ring 241 is used to contact with the inner wall of the slot of the insertion slot 211 to limit the separation of the center rod 24 from the insertion slot 211, and meanwhile, the excessive movement of the support 21 toward the outside of the base 2 is avoided, thereby improving the structural stability of the device.

In this embodiment, the first protrusion 372 is above the second protrusion 373.

A bolt 374 is arranged between the two splicing plates 37, and the bolt 374 is suitable for being in threaded connection with the first threaded hole 3721 and the second threaded hole 3731.

The locking member 33 is a rod that penetrates the sliding member 32 in the vertical direction and is inserted into one of the positioning holes 35. When the locking member 33 penetrates the sliding member 32 in the vertical direction and is inserted into one of the positioning holes 35, the movement of the sliding member 32 in the horizontal direction is restricted because the outer peripheral wall of the locking member 33 comes into contact with the inner wall of the positioning hole 35.

Referring to fig. 2 to 3, as an embodiment of the automatic lifting base for a material distributing machine according to the present invention, an outer edge of the base 2 coincides with an outer edge of the vertical base 1, and the upper end of the base 2 is open.

Through adopting above-mentioned technical scheme, improved the structural stability of this device to and convenience, reliability when the in-service use.

The beneficial effects of the above technical solution are explained as follows:

because the outer edge of the base 2 coincides with the outer edge of the vertical seat 1, when the base 2 adopts a structure with an open upper end, the structure in the base 2 is not exposed to the outside.

Due to the opening at the upper end of the base 2, after the base 2 is separated from the vertical seat 1, a worker can adjust, maintain and maintain the internal structure of the base 2 through the opening of the base 2, and the convenience of the device in actual use is improved.

When the outer edge of the base 2 is located in the outer edge of the standing seat 1, the supporting member 21 needs to extend out of the outer edge of the standing seat 1, and the extending amount of the supporting member 21 is inversely proportional to the strength of the supporting member 21 (the more the supporting member 21 extends, the more easily the bending phenomenon of the extending part of the supporting member 21 occurs), so the structural stability of the device can be improved by adopting the technical scheme.

When the outer edge of the pedestal 2 is not the outer edge of the stand 1, the stand 1 may pass through the prepared hole 300 and the pedestal 2 may not pass through the prepared hole 300. Because the preformed hole 300 is certainly suitable for the vertical seat 1 to pass through, adopt above-mentioned technical scheme can avoid the integrated configuration of vertical seat 1 and base 2 can't pass through the phenomenon of preformed hole 300, improved the reliability of this device when in actual use.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
