Abstract

The utility model relates to a manual concrete distributing rod which relates to a concrete conveying machine and is used in places of distributing concrete; the utility model is mainly composed of a bottom frame (1), a tower frame (12), a back arm rod (15), a front arm rod (23), rope rolling wheels (8) and (30), a rotary wheel (21), steel cables (10) and (11), etc; after the tower frame (12) is arranged, a definite height can be achieved, the utility model can not be influenced by peripheral obstacles when the concrete distributing work is carried out, and simultaneously, the utility model can be used in places of casting wall bodies. After the utility model is lifted, the rotation of the front arm rod (23) is controlled by a pulley group of the steel cable; after the tower frame is disassembled, the height is reduced, and the ground concrete distributing work can be convenient to carry out; so, the utility model has the advantages of simple structure, convenient operation, low cost and wide serviceability.

Description

A kind of manual concrete placing boom

The utility model relates to concrete conveying machinery, is a kind of novel manual concrete placing boom, is applied to the concrete distributing engineering.

Though at present the hand-operated simple boom that uses can carry out the concrete distributing operation of ground line, runs into the obstacle that is above the ground level,, then can not carry out operation as vertical reinforcing bar etc.; Must rely on artificial stringing or select expensive hydraulic pressure boom for use, just can finish the concrete distributing operation.

The purpose of this utility model provides a kind of simple in structure, and is easy to operate, cheap, the manual concrete placing boom that applicability is wider.

Feature of the present utility model is: utilize pylon to increase height of devices, utilize wire rope, bull wheel, pulley and gyroscope wheel to finish the revolution of preceding armed lever.

Accompanying drawing 1 is a structural representation of the present utility model.

Accompanying drawing 2 is that wire rope of the present utility model twines schematic diagram.

Among the figure: [1] is underframe, [2] be positioning disk, [3] be hollow vertical shaft, [4] be bearing A, [5] be swivel base next time, [6] be balancing weight, [7] be latch A, [8] be right rope rolling wheel, [9] be bearing pin A, [10] be left wire rope, [11] be right wire rope, [12] be pylon, [13] be right pulley, [14] be bearing pin B, [15] be the back armed lever, [16] be middle carrier pipe, [17] be pipe collar B, [18] be last carrier pipe, [19] be pipe collar C, [20] be bearing B, [21] be gyroscope wheel, [22] be pull bar, [23] be preceding armed lever, [24] be pipe collar D, [25] be flexible pipe, [26] pipe collar A, [27] be following carrier pipe, [28] be latch B, [29] be bolt, [30] be left rope rolling wheel, [31] be left chain wheel.

Existing accompanying drawings structure of the present utility model and operation are down:

Positioning disk [2] is welded on the top of underframe [1], and hollow vertical shaft [3] and underframe [1] connect.Swivel base [5] is by bearing A[4 next time] be installed on the hollow vertical shaft [3], swivel base [5] is used latch B[28 next time] and underframe [1] relative positioning.Balancing weight [6] is placed on the afterbody of swivel base [5] next time.The two ends bearing pin A[9 of pylon [12]], bearing pin B[14] connect with swivel base [5] next time, back armed lever [15] respectively.Before armed lever [23] by bearing B[20], pull bar [22] location, use pipe collar C[19] connect with last carrier pipe [18].Flexible pipe [25] is used pipe collar D[24] be suspended in the front end of preceding armed lever [23].Preceding armed lever [23] is made of the elephant trunk of bending.Gyroscope wheel [21] is solidly set on the preceding armed lever [23].Left chain wheel [31] and right pulley [13] are installed in the both sides of armed lever [15] rear end, back respectively.Bolt [29] with right rope rolling wheel [8] and left rope rolling wheel [30] rigid connection together, latch A[7] with right rope rolling wheel [8] and swivel base [5] relative positioning next time.Left side wire rope [10] is walked around left chain wheel [31], and two ends connect with left rope rolling wheel [30] and gyroscope wheel [21] respectively; Right wire rope [11] is walked around right pulley [13], and two ends connect with right rope rolling wheel [8] and gyroscope wheel [21] respectively.Following carrier pipe passes hollow vertical shaft [3], uses pipe collar A[26] connect with middle carrier pipe [16]; Middle carrier pipe [16] is used pipe collar B[17] connect with last carrier pipe [18]; Last carrier pipe [18] is used pipe collar C[19] connect with preceding armed lever [23].

When carrying out the concrete distributing operation, if when erecting obstructions such as reinforcing bar is arranged around the underframe [1], then as shown in Figure 1, extract latch B[28], hand push is the afterbody of swivel base [5] next time, can make underframe [1] realize revolution at any angle easily, and then install latch B[28 with upper-part], incite somebody to action swivel base [5] and underframe [1] relative positioning next time.When needing before the revolution armed lever [23], extract latch A[7], the right rope rolling wheel that turns left [8], the right wire rope [11] of right rope rolling wheel [8] rolling then, left rope rolling wheel [30] loosens left wire rope [10], thus armed lever [23] turns left before realizing; Otherwise, can realize that then preceding armed lever [23] turns right.Before armed lever [23] revolution finish, install latch A[7], make right rope rolling wheel [8] and swivel base [5] relative positioning next time.Because bolt [29] can be with left rope rolling wheel [30] and right rope rolling wheel [8] rigid connection together, so during the preceding armed lever [23] of revolution, can single or double operation.Remove flexible pipe [25], the utility model then can be used for implementing the concrete distributing of body of wall.

If there is not too high obstruction around the underframe [1], can remove pylon [12], middle carrier pipe [16] and flexible pipe [25], back armed lever [15] is directly installed on next time on the swivel base [5], last carrier pipe [18] links with following carrier pipe [27], remove bolt [29], left wire rope [10] more than needed is wrapped on the left rolling wheel [30]; Right wire rope [11] more than needed is wrapped on the right rope rolling wheel [8].At this moment with hand propelled swivel base [5] or preceding armed lever [23] revolution next time, just can carry out the concrete distributing operation of ground line.

The utlity model has advantage simple in structure, easy to operate, cheap, that applicability is wider.
