Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, unless otherwise specified, the use of directional terms such as "upper, lower, left, and right" generally means upper, lower, left, and right as illustrated with reference to fig. 1; "inner and outer" refer to the inner and outer relative to the profile of the components themselves. The present invention will be described in detail with reference to the accompanying drawings in conjunction with embodiments.

The problem of when equipment such as crane, tower crane in the building construction hoists longer shaft-like material, take place the pole material slope easily and then drop from the sky and cause serious incident is solved in order to solve. The utility model provides a pole material lifting appliance, as shown in figures 1 and 2, which comprises a telescopic rod 2, wherein the length of the telescopic rod 2 is variable and is fixed by a set screw 5; the two ends of the telescopic rod 2 are respectively connected with an end sleeve 1, the end sleeves 1 are cylindrical, one ends of the end sleeves 1 are open, the axes of the two end sleeves 1 are overlapped, the openings of the two end sleeves 1 are opposite, and the telescopic rod 2 is parallel to the axis of the end sleeve 1; the end sleeve 1 is fixed with a hanging ring 3.

The utility model relates to a pole material hoist, it is exactly that the pole material both ends of treating the hoist and mount overlap separately and establish an end cover 1, then directly come to the pole material hoist through the mode of the end cover 1 that lifts up both sides. So the axes of the two end sleeves 1 are overlapped and the openings of the two end sleeves 1 are oppositely arranged. The end sleeve 1 is just like the end sleeve 1 shown in the figure, and one end of the end sleeve 1 is open, and the other end of the end sleeve is closed, so that after the left end sleeve 1a is sleeved, the closed end of the end sleeve 1 is pressed against the end surface of the rod material, and the end sleeve can only move in the opposite direction to be separated from one end of the rod material. Therefore, the two end sleeves 1 are connected together through the telescopic rod 2, the length of the telescopic rod 2 can be adjusted through telescopic sliding, and then the distance between the two end sleeves 1 is changed to adapt to rod materials with different lengths. The extending direction of the telescopic rod 2 is parallel to the axis of the end sleeves 1, and the two end sleeves 1 can always keep the axes coincident when the telescopic rod 2 performs telescopic motion, so that dislocation cannot occur. The length of the telescopic rod 2 is locked by the set screw 5, so that the two end sleeves 1 cannot move reversely to cause the end sleeves 1 to be separated from one end of the rod material during hoisting. The cross section of the end sleeve 1 can be circular or square, and is not limited to a specific cross section. Preferably, as shown in fig. 1 and 2, the end sleeve 1 is circular, and the material of the end sleeve 1 is metal or metal alloy. Hoisting operation is carried out in the building construction, and the hoisting operation is not similar to the hoisting operation carried out in a factory, and overweight loads can not be hoisted generally, so the end sleeve 1 can be made of aluminum alloy with lighter weight and proper price, and the aluminum alloy also has better corrosion resistance. The same material for same whole device, telescopic link 2 is the aluminum alloy material too, and telescopic link 2 is through welding and end cover 1 fixed connection. One mode is that one end of a telescopic rod 2 is welded and fixed on the end surface of one side of the opening of an end sleeve 1; the other mode is to weld and fix one end of the telescopic rod 2 on the outer side surface of the end sleeve 1.

The telescopic rod 2 specifically comprises two main parts, namely a sleeve 2a and a sleeve rod 2b, as shown in fig. 1 and 2, one end of the sleeve 2b is sleeved with the sleeve 1 at one end of the sleeve 2a, while the sleeve rod 2b can slide in the sleeve 2a, the other end of the sleeve 2a is fixedly connected with the left end sleeve 1a, and the other end of the sleeve rod 2b is fixedly connected with the right end sleeve 1 b. The left end sleeve 1a and the right end sleeve 1b are only named for convenience of description, and two completely different components are not limited to the invention. The holding screw 5 is installed in the side of sleeve pipe 2a and is kept away from the one end of end cover 1, guarantees like this that also can lock telescopic link 2 when telescopic link 2 reaches the maximum flexible length. When the set screw 5 is screwed inwards, the tail part of the set screw 5 abuts against the side edge of the sleeve rod 2b to limit the sliding of the sleeve rod 2b relative to the sleeve 2 a. Since the side wall of the sleeve 2a is thin, a female screw tube 6 is provided on the side surface of the sleeve 2a, and the set screw 5 is attached to the female screw tube 6. The loop bar 2b is detachable from the sleeve 2 a.

As shown in fig. 2, two end sleeves 1 are connected through more than one telescopic rod 2, and since the telescopic rod 2 is connected to the side surface of the end sleeve 1, disabling one telescopic rod 2 can cause the telescopic rod 2 to receive bending moment, which is not beneficial to the normal operation of the telescopic rod 2, so that a plurality of telescopic rods 2 are preferably distributed on the peripheral surface of the end sleeve 1 at equal intervals. Therefore, the telescopic rods 2 can only bear axial force due to the uniform stress of the telescopic rods 2. However, too many telescopic rods 2 are not favorable for arranging the rods into the two end sleeves 1. Therefore, the two telescopic rods 2 are further preferred, so that the two telescopic rods 2 can be uniformly stressed, and the phenomenon that the telescopic rods 2 influence the operation too much is avoided. As shown in fig. 1, if the telescopic rod 2 is arranged below the end sleeve 1, the telescopic rod 2 below the lifting appliance after falling to the ground can be pressed below the rod material and cannot be detached, so in order to avoid this, the telescopic rods 2 are arranged on two sides of the end sleeve 1, and the two telescopic rods 2 are fixed on two sides of the end sleeve 1, namely in the up-and-down direction in fig. 2. Similarly, in order to avoid interference between the hoisted rod and the female screw tube 6 and to prevent the set screw 5 from being operated, it is preferable that the female screw tube 6 extends in a direction away from the axis of the end sleeve 1. As shown in fig. 2.

The utility model discloses a pole material hoist still including lifting

rope

4, 4 both ends of lifting rope are connected respectively in rings 3 of two pot caps 1, and the apparatus of hoist and mount just so need not be connected with two rings 3 simultaneously, but only need be connected with lifting rope 4, can apply an inside component to pot cap 1 at the process lifting rope 4 of hoist and mount moreover, even when telescopic link 2 takes place not hard up, also can further avoid the tubular product both ends to break away from the possibility of pot cap 1. The middle part of the lifting rope 4 is fixed with a lifting hook 7, which is convenient for devices such as a crane and the like to directly hook and hoist.

The utility model discloses a working method: at first, stretch telescopic link 2, let two end sleeves 1 keep away from the interval of the opening terminal surface of end sleeve 1 each other and be greater than the pole material of treating the hoist and mount, then set up two end sleeves 1 in the both sides at pole material both ends, then shorten two end sleeves 1 covers of telescopic link 2 and establish at the both ends of pole material, after pole material withstood two end sleeves 1, screw up holding screw 5 and can be connected the pole material hoist of treating the hoist and mount as an organic whole. Then the hook on the lifting rope 4 is hooked to realize the lifting operation.

The above-mentioned embodiments are only described for the preferred embodiments of the present invention, and are not limited to the scope of the present invention, and the ordinary skilled person in the art can modify and improve the technical solution of the present invention without departing from the design spirit of the present invention, including using the present invention in old house decoration, and all should fall into the protection scope defined by the claims of the present invention.
