Referring to fig. 1 to 4, a balustrade 2 performance detecting apparatus includes:

a base 1;

the lifting seat 3 is arranged on the base 1, is hollow and is open;

a lifting plate 4 inserted from the open end of the lifting seat 3 in a sliding manner;

a fixing member 5 separating or connecting the lifting base 3 and the lifting plate 4;

and the performance detection device 6 is arranged on the lifting plate 4.

The base 1 is buried on the ground through the expansion bolts. The height of the lifting plate 4 relative to the ground can be adjusted by adjusting the height of the lifting plate 4 in the lifting base 3 and connecting by the fixing member 5. During the use, adjust lifter plate 4 to the same height with railing 2, utilize performance detection device 6 to detect the performance of railing 2. The device has the advantages that the height of the lifting plate 4 can be adjusted, so that the lifting plate 4 of the device can be retracted into the lifting seat 3, the size is reduced, and the carrying is convenient; in addition, 4 high railings 2 that can also adapt to outdoor multiple height of lifter plate can be adjusted, improve adaptability, and this makes and need not raise this device with the help of other objects, and efficiency has improved.

Further, the fixing member 5 is a limiting rod;

a plurality of first limiting holes 31 communicated with the inside and the outside are respectively formed in two side walls of the lifting seat 3; the first limiting holes 31 on the two side walls of the lifting seat 3 are arranged in a one-to-one correspondence manner; the lifting plate 4 is provided with a second limiting hole 41; the limiting rod passes through two first limiting holes 31 on two side walls of the lifting seat 3 and passes through a second limiting hole 41 on the lifting plate 4.

The lifting plate 4 is matched with the inner cavity of the lifting seat 3 in shape; specifically, the lifting plate 4 is a rectangular parallelepiped, and the inner cavity of the lifting base 3 is also a rectangular parallelepiped. The lifting plate 4 slides to a proper position in the inner cavity of the lifting seat 3, the second limiting hole 41 on the lifting plate coincides with the two horizontal first limiting holes 31 of the lifting seat 3, and the lifting plate 4 is fixed in the lifting seat 3 by inserting a limiting rod into the first limiting hole 31 and the second limiting hole 41; when the height is changed, the operations are repeated, and the first limiting hole 31 and the second limiting hole 41 with different levels are selected to be overlapped and are overlapped by the limiting rod. It should be noted that the first limiting holes 31 on one side of the lifting seat 3 may be two vertical rows, and correspondingly, the second limiting holes 41 on the lifting plate 4 are also two vertical rows, so that two limiting rods are required.

Further, two columns of second limiting holes 41 are vertically arranged on the lifting plate 4, and the distance between two adjacent second limiting holes 41 in the same column of second limiting holes 41 gradually increases from bottom to top; two lines of first limiting holes 31 which are vertically arranged are respectively formed in two sides of the lifting seat 3.

When the height of the lifting plate 4 is adjusted, the two second limiting holes 41 at the lowest end are overlapped with the first limiting holes 31 at each level and are locked by the limiting rods, so that the lifting plate 4 can be lifted at a certain interval. The distances between the second limiting holes 41 in the same column are different, so that the second limiting holes 41 in different rows can be used to coincide with the first limiting holes 31 in different rows, and various combinations can be obtained, so that the height of the lifting plate 4 can be adjusted more finely.

Further, the performance detection device 6 includes a bearing capacity detection mechanism 61;

the bearing force detection mechanism 61 includes:

a jack 611 installed on the lifting plate 4;

a detection sleeve 612, one end of which is closed and is slidably sleeved on the piston rod of the jack 611;

a force sensor 613 which is arranged on the inner wall of the closed end of the detection sleeve 612 and is abutted against the end part of the piston rod of the jack 611;

a display device 614 is mounted outside the detection sleeve 612 and electrically connected to the force sensor 613.

The jack 611 adjusted to a proper height abuts the sensing sleeve 612 against the balustrade 2 through the piston rod. By adjusting the pressure of the jack 611 on the balustrade 2, whether the balustrade 2 is damaged or not under the application of a qualified external force is detected. I.e. the process is repeated. When the display 614 reads to be within the acceptable range, the balustrade 2 is normal. It should be noted that the display device 614 is implemented in the prior art, and the purpose of the display device is to convert the data of the thermal sensor into a visible number for comparison by the operator.

Further, the performance detection device 6 further includes a rigidity performance detection mechanism 62;

the rigidity performance detection mechanism 62 includes:

a support member 621 mounted on the lifting plate 4;

a wire rope 622 having one end connected to the balustrade 2 and the other end connected to a spring load cell 623 by passing around the support member 621;

wherein, a weight 624 is hooked under the spring dynamometer 623, and the supporting member 621 is used for adjusting the steel wire rope 622 between the supporting member and the railing 2 to be horizontal and displaying the moving distance of the steel wire rope 622 to the weight 624 through the supporting mechanism.

By increasing the point that the weight 624 at the lower end of the spring load cell 623 passes through the leveling member to pull the handrail 2, it can be seen that when the weight 624 is increased to a specified weight (the spring load cell 623 can read the increased amount of the weight 624), the steel wire rope 622 pulls the handrail 2 by a displacement amount, and if the deformation amount of the handrail 2 is small at this time, that is, the distance that the steel wire rope 622 downwardly displaces through the supporting member 621 is small, the requirement of rigidity performance is met. It will be appreciated that different balustrades 2 require different stiffness properties, so a spring load cell 623 is required to identify the weight 624 under different balustrades 2.

Further, the support member 621 includes a scale shaft 621a;

the wire rope 622 vertically rounds the scale shaft 621a and then is connected with the spring dynamometer 623, and scales are arranged on the outer peripheral wall of the scale shaft 621a along the circumferential direction.

The wire rope 622 is attached to the scale shaft 621a to move, and a mark is made on the wire rope 622, for example, the wire rope 622 is painted with chalk, and the mark of the painted wire rope 622 is located on a certain scale of the scale shaft 621 a. When the weight of the weight 624 reaches the standard and is hooked on the spring dynamometer 623, the steel wire rope 622 pulls the railing 2 to move under the driving of the weight 624, the steel wire rope 622 moves around the scale shaft 621a, the mark on the steel wire rope 622 moves along the scale of the scale shaft 621a until the mark stops, the reading (the deformation of the railing 2 at the moment) at the moment is recorded, and the weight of the weight 624 is referred to, so that whether the rigidity performance requirement is met can be checked.

Further, the supporting member 621 further includes:

two positioning rods 621b are arranged, and the upper ends of the two positioning rods are connected with anti-falling blocks 621h;

a square fixing ring 621c connected to the lifting plate 4;

four support bars 621e arranged in parallel are respectively connected to four corners of the square fixing ring 621c and are obliquely arranged relative to the lifting plate 4;

the four corners of the inverted U-shaped block 621d are respectively connected with one end of the supporting bar 621e far away from the square fixing ring 621 c;

each supporting bar 621e is provided with a plurality of vertically penetrating positioning holes 621f along the length direction; two ends of the scale shaft 621a are respectively provided with a matching hole 621g which vertically penetrates downwards; the scale shaft 621a is transversely arranged between the four support bars 621e on the upper side and the lower side; one end of the positioning rod 621b passes through the positioning hole 621f on the upper support bar 621e and then passes through the matching hole 621g on the scale shaft 621a and the positioning hole 621f of the lower support bar 621 e.

Two positioning rods 621b are provided to position two ends of the scale shaft 621a, respectively, and since the supporting bar 621e is disposed obliquely relative to the lifting plate 4, the supporting bar 621e is also disposed obliquely relative to the balustrade 2. When the steel cable 622 is connected to the balustrade 2, it is found that the portion between the steel cable 622 and the scale shaft 621a is not horizontal, and the force of the weight 624 acting on the balustrade 2 has a component force in other directions, which results in a measurement error. Therefore, the height of the scale shaft 621a needs to be adjusted until the steel cable 622 between the handrail 2 and the scale shaft 621a is horizontal. The specific method is that the positioning rods 621b are taken down, the height (inclined direction sliding) of the scale shaft 621a between the supporting bars 621e is moved until the steel wire rope 622 between the scale shaft 621a and the railing 2 is horizontal, and then two positioning rods 621b are used for locking two ends of the scale shaft 621a on the supporting bars 621 e. The inverted U-shaped block 621d is different from the square fixing ring 621c in that the inverted U-shaped block gives way to the steel wire rope 622 when fixing the four supporting bars 621e, so as to avoid contact with the steel wire rope 622, and facilitate direct contact between the steel wire rope 622 and the scale shaft 621 a.

In the specification of the present invention, a large number of specific details are explained. It is understood, however, that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.
