When the cloth radius is reduced, it means that the span of the telescopic legs can be reduced.
- P1 to P4 are the upward counter-supporting forces (referred to as ground reaction forces) of the ground-to-legs received by the four support points of the telescopic legs.
- the dotted circle is the circle of gravity of the center of gravity of the cloth equipment (such as concrete pump truck).

- the three equations in (3) can be given by the following equation (4): It can be seen from the formula (4) that there is a positive correlation between the size of P2 and the circle radius R1 of the center of gravity of the cloth equipment.
- the circle radius R1 of the center of gravity of the cloth device is also reduced.
- the span of the telescopic legs ie, the lateral span and the front and rear spans
- the quadrilateral can include the trajectory circle of the center of gravity of the whole machine.
- the span of the legs is determined by the maximum fabric radius of the fabric boom, while the construction conditions for the fabric equipment (such as the long-arm concrete pump truck) are higher and higher. This is also the realistic requirement for the cloth equipment to continuously increase the maximum fabric height. If you can reduce the radius of a part of the fabric while ensuring the maximum fabric height, as described above, the span of the legs can be reduced, the span is reduced, and the reduction can be made by appropriately setting the reduction value of the leg span.

- further modifications are actually included in the protection scope of the above basic embodiment. Regardless of the number of arm segments locked in the vertical state, the locking should be sequentially performed from the first segment of the arm segment. Otherwise, During the cloth operation, if the first section of the arm section 2 can Free movement, it will destroy the vertical state of the rear arm section.
- the main technical idea of the present invention is to provide a cloth control method by which the cloth is controlled.

- a concrete pump truck adopts the fabric control method of the present invention, it can be designed accordingly.
- the support span of the telescopic legs is reduced, thereby achieving a relatively small overall weight.
- the cloth apparatus implements the fabric method of the present invention, although it can adopt specially designed control technology, these control techniques are not The necessary components of the invention, even without the use of these control techniques, are achievable by manual operation by the operator, for example by manual operation by the operator using a latch locking mechanism to achieve complete locking of the vertical state of the first section of the arm section. It is achievable; for example, the first arm section 1 is additionally supported by a corresponding mechanical automatic arm to fix it in a vertical state. That is, the above-described fabric apparatus cloth control method of the present invention is not limited to the implementation by a specific control technique, and any cloth apparatus as long as it employs the cloth control method of the present invention is within the scope of the present invention.
- the present invention provides a cloth distributing apparatus, the cloth boom 1 of the cloth apparatus comprising at least two arm sections that are hinged in sequence and foldably extendable relative to each other, wherein the cloth apparatus further includes The first section of the boom 1 of the boom 1 locks the locking device in a vertical position.
- the lock device can be simply a simple latch lock mechanism, for example,
- the corresponding bracket plate is fixed on one arm section 2, and when the first section arm section 2 is in the vertical state, the pin hole on the bracket plate on the first section arm section 2 is matched with the cloth device (for example, the turntable).
- the holes are aligned, and the pin is inserted into the pin hole and the matching hole of the bracket plate, so that the first arm section 2 can be easily locked in the vertical state.
- the arm section locked in the vertical state includes at least two arm sections of the first section of the first section of the arm section, a corresponding bracket plate having the pin hole is disposed between the first section arm section and the second section arm section After the first section of the arm section is locked, the second section of the arm section is locked to the first section of the arm section by the similar latch described above, and so on, and will not be described again.
- the winding device for example the locking device on the concrete pump truck
- the winding device is mainly realized by hydraulic control technology, most simply between the first pitch arm 2 of the cloth boom 1 and the support base of the cloth device (for example the turntable) And adjacent Hydraulic cylinders are respectively hinged between the arm joints, wherein the hydraulic telescopic control circuit of the hydraulic cylinder hinged between the first pitch arm joint 2 and the support base of the distributing device is provided with a telescopic reversing
- the control reversing valve is a 0-type three-position four-way reversing valve, and the 0-type three-position four-way reversing valve doubles as the locking device. Specifically, when the first section arm section 2 is moved to the vertical state, the 0-type three-position four-way reversing valve is switched to the middle position, and the first section arm section can be locked in the vertical state by the center cut function. .
- the reversing valves on the telescopic control circuits of the respective hydraulic cylinders between adjacent arm sections of the cloth boom 1 are respectively 0-type three-position four-way reversing valves.
- the position of each of the other arm segments described above can be easily locked by the median function of the 0-type three-position four-way reversing valve.
- the 0-type three-position four-way reversing valve has basically realized the locking function of the hydraulic cylinder.
- a balancing valve can be further added to realize the locking function, which can be realized by various technical measures for those skilled in the hydraulic field, and will not be described herein.
- the present invention mainly provides a cloth control method different from the conventional form, for example, in the case of a commonly used concrete pump truck, the concrete pump truck is in the telescopic leg. After being unfolded and supported, after the first arm arm section 2 is unfolded and moved to the vertical state, the first section arm section 2 is locked by locking the hydraulic cylinder hinged between the first section arm section 2 and the turntable In the vertical state, in this case, the other arm sections are first unfolded in sequence, and then the corresponding arm section extension folds can be arbitrarily controlled to perform the cloth work.
- the present invention has an advantage in that: the present invention provides an original cloth material distributing operation method, in which at least the first arm section 2 is locked in a vertical state during the cloth operation, and in other arms After the section is unfolded, it is controlled according to the fabric to perform the corresponding stretching or folding movement for the cloth work. That is to say, the fabric control method of the present invention allows the fabric apparatus to reduce the support span of the leg by artificially abandoning a part of the fabric radius while ensuring the maximum fabric height, and to support the span by a reasonable arrangement.
- the reduction value makes it possible to reduce the strength of the leg 3, so that the size of the telescopic leg can be reduced, and the corresponding reinforcing member is reduced, thereby effectively achieving the purpose of weight reduction of the cloth device, and effectively ensuring the cloth. Stability and safety when the equipment is clothed.
- the method of weight reduction is mainly through material improvement, that is, the use of carbon fiber to manufacture the boom or other parts, and the invention is made by the original fabric control method
- the cloth apparatus is used to implement the cloth control method, and thus it also has the above advantages.
