A kind of truss transport support of adjustable supporting height
The truss transport of the metal truss the present invention relates to be used in transportation support escalator or moving sidewalk
The truss transport support of support, especially a kind of adjustable supporting height.
In the prior art, the metal truss of escalator or moving sidewalk is all according to actual stride design processing
Into, and be all transported to after being assembled in factory it is field erected.Because the span of metal truss is big, incline with certain
Rake angle, takes up space larger, and do not allowed in transportation by more than two metal truss be directly stacked upon together, with
A metal truss can only be filled toward a van, cost of transportation is higher.In order to reduce cost of transportation, truss is occurred in that in recent years
Transport support, it is real with laminated metal truss indirectly dedicated for being supported to metal truss during transport metal truss
The purpose of the existing multiple truss of train number shipment, improves the space availability ratio of van, reduces escalator or moving sidewalk
Metal truss cost of transportation.
But, current truss transport support is all the support of fixed structure, can only be exclusively used in fixing the metal purlin of specification
The support of frame, so range of application is limited.Metal truss transport for plurality of specifications needs to prepare various different sizes again
Support, it is cumbersome.Therefore, a kind of adjustable supporting height of exploitation is needed badly to adapt to the branch of the metal truss of different size specification
Support and stacking are placed.
The content of the invention
In view of this, it is an object of the invention to provide a kind of truss transport support of adjustable supporting height, truss fortune
Defeated support can be directed to the metal truss quick regulation bearing height that different size specifies, extend bearing height scope, and it is right to reach
The versatility of plurality of specifications metal truss support.
To reach above-mentioned purpose, the present invention provides a kind of truss transport support of adjustable supporting height, it is characterised in that：
The frame upper in a support bottom is plugged on respectively including a pair of brackets bottom, two ends, and each described support bottom has
The bottom for having the slot of upper opening, the slot offers multiple bayonet sockets along short transverse interval；The frame upper includes
Cross bar and it is connected to the two ends of the cross bar and extends downwardly the vertical rod of the pluggable slot；The truss transport support
Also include being detachably connected in the bayonet socket support the support member of the vertical rod.
Preferably, the support bottom includes the diagonal brace angle steel that bottom angle steel and a pair of angled are set, the bottom angle steel
Surround to form triangular structure with the diagonal brace angle steel, the support bottom also includes the top down from the triangular structure
Extension and the bottom angle steel rectangular tube connected vertically, diagonal brace angle steel is connected to the two of the rectangular tube described in a pair
Side, the hollow cavity and upper opening of the rectangular tube form the slot.
It is highly preferred that the vertical rod is the square steel being slidably matched with the rectangular tube.
Preferably, on the sustained height of the slot, at least two bayonet sockets are offered.In sustained height using two cards
Mouthful and corresponding two support members support jointly, bearing capacity and security can be improved, it is to avoid because of branch after a support member fracture
The danger that frame collapses.
In one embodiment, the support member is bolt assembly.
The truss transport support that the present invention is provided, simple structure is easy for installation, selects to connect by dismountable support member
In the bayonet socket of the different height of support bottom, the regulation of different bearing heights is realized such that it is able to for supporting and stacking difference
The metal truss of dimensions, it is very convenient.

Specific embodiment of the invention is described in detail below in conjunction with the accompanying drawings.
Refer to Fig. 1 to 5, a kind of truss transport support of adjustable supporting height, including a pair of brackets bottom 1, two ends
The frame upper 2 in a support bottom 1 is plugged on respectively, and each support bottom 1 has the slot 10 of upper opening, described
The bottom of slot 10 offers multiple bayonet sockets 101 along short transverse interval；Frame upper 2 includes cross bar 21 and is connected to horizontal stroke
The two ends of bar 21 simultaneously extend downwardly the vertical rod 22 of the pluggable slot；The truss transport support also includes detachably connected
With the support member 3 of supported rod erecting 22 in bayonet socket 101.
As shown in figure 3, support bottom 1 includes the diagonal brace angle steel 12 and rectangular tube 13 that bottom angle steel 11, a pair of angled is set,
Bottom angle steel 11 and diagonal brace angle steel 12 are surrounded and form triangular structure, and rectangular tube 13 prolongs from the top down of the triangular structure
Stretch it is vertical with bottom angle steel 11 be connected, a pair of diagonal brace angle steel 12 are connected to the both sides of rectangular tube 13, rectangular tube 13 it is hollow
Inner chamber and upper opening form slot 10.And, a pair of length of diagonal brace angle steel 12 of support bottom 1 are identical, and are symmetrical arranged.Institute
Triangular structure with the formation of support bottom 1 is as isosceles triangle.The bottom of rectangular tube 13 is on four different height and positions
Four groups of bayonet sockets 101 are offered successively, and every group of bayonet socket 101 is two.Bayonet socket 101 in the present embodiment is for wearing through bolt
As shown in Figures 4 and 5, the cross bar 21 of frame upper 2 is channel-section steel, and two ends are respectively welded vertical rod 22, vertical rod 22 be with
The square steel that the rectangular tube 13 of support bottom 1 is slidably matched.After the insertion rectangular tube 13 of vertical rod 22, by the support member 3 through bayonet socket 101
Support.Support member 3 in the present embodiment is bolt assembly, including bolt, nut and pad.During connection, bolt is from hollow square
Through then being fixed with pad and nut check, bolt support can be stablized shape pipe 13 in the lower end of vertical rod 22, therefore vertical rod 22
Stand in rectangular tube 13.The each lower end of vertical rod 22 is all supported by two bolt assemblies.What operating personnel transported as needed
Metal truss size, selects one group of bayonet socket of different height, and bolt assembly is connected on bayonet socket 101, realizes bearing height
Regulation, it is very convenient.
The above embodiments merely illustrate the technical concept and features of the present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implement according to this that it is not intended to limit the scope of the present invention, all according to the present invention
The equivalent change or modification that Spirit Essence is made, should all be included within the scope of the present invention.
